DR/820 Portable Colorimeter Datasheet

Features and BenefitsChoose from Three ModelsDepending on your testing needs, you can select a DR/820, DR/850 or DR/890 Colorimeter, preprogrammed to test for at least 20, 50 or 90 parameters, respectively. All three models include the same convenient features: auto-wavelength selection, datalogging capabilities anduser-generated calibrations. Refer to the table on pages 3-4 to select the colorimeter that tests the parameters you require. These durable, hand-held, filter photometers are designedspecifically for the rigors of on-site testing, with ruggedcomponents and waterproof, dustproof, chemical-resistanthousings. DR/800 Series Colorimeters offer simple, push-button program selection and step-by-step promptsthat guide users through the testing procedure. Theseinstruments are equally appreciated by experienced analystswho value test efficiency and by operators who require easeof use with accurate results. Advanced Features Add Value• Easy-to-use software offers push-button methodselection, automatic wavelength selection and apreprogrammed method timer. Result, units, andparameter name are displayed immediately, with nocountdown. The large digit display is very easy to read. • The DR/800 retains the selected method until a newmethod is entered, even if it is turned off and then backon. This allows a series of analyses to be performed forthe same parameter without reselecting the method.• Datalogging capability includes push-button recordmanagement. Easily store data in the field for later access,with no delay in testing. The instrument stores up to 99measurements in an internal, non-volatile memory. Datastored includes date/time, parameter, program number,concentration/absorbance/%T, sample number, andinstrument serial number.• Results are displayed directly in units of concentration,absorbance, or % transmittance. In many methods,concentration in alternate chemical forms is also available.For example, phosphate readings are available as P, PO4and P2O5. Displayed results can be changed from oneform to the next at the touch of a button.• User-program feature allows users to generate up to 10 custom procedures, with up to 12 data points each,and store them in a non-volatile instrument memory forlater use.• Advanced software includes automatic correction forreagent blanks and the option to fine-tune calibrationcurves with the standard adjust feature.• Batteries provide self-contained power for field-testing. Accessories Simplify Data ManagementThe Data Transfer Adapter (DTA) fits on the colorimeter andaccepts data sent from the instrument’s infrared LEDtransmitter. The DTA converts data to a standard RS-232format and connects directly to a computer or printer. Datacan be printed or downloaded conveniently, after storage orduring collection. DR/800 Series Colorimeters are compatible with HachLink™Software, a Microsoft® Windows® compatible applicationthat links instrument and computer, providing a convenientmeans of accessing and managing test data. Informationincluding date/time, parameter, concentration/absorbance/%T,sample number, operator identity, and instrument serialnumber is accepted and stored in either text or tabular(spreadsheet) format, and can be easily transferred topopular spreadsheet or word-processing applications. Easy Quality ControlDR/Check™ ABS Standards are the optional choice to verifythe performance of your DR/800 Colorimeter in seconds.Standards are formulated with neutral density gel thatproduces similar absorbance readings at any wavelength.For all parameters at all wavelengths, running threesecondary absorbance standards will verify yourinstrument’s calibration easily, anytime.DR/800 Series ColorimetersMulti-parameter analysis in the palm of your handDW = drinking water WW = wastewater municipal PW = pure water / power IW = industrial water E = environmental C = collections FB = food and beverageDATA SHEETColorimeterDWWWPWIWEFBHach DR/800 Series Colorimeters combine ease of use,multiple testing capabilities and field readiness. Analysisrequires minimal time and preparation, with results displayeddirectly on the large liquid-crystal display in concentration,percent transmittance, or absorbance units.2Features and Benefits continuedAffordable COD AnalysisAll three models include Hach’s Manganese III COD procedure (mercury-free version).The DR/850 Colorimeter also performs our traditional USEPA-approved high-rangeCOD procedure, and the DR/890 Colorimeter performs both low-range and high-rangeUSEPA-approved COD procedures. An adapter suitable for COD vials and Test ’NTube™ (TNT) vials is included with each instrument.Push-Button Operation Speeds AnalysisUsing Hach prepared reagents, testing is normally accomplished in just a few minutes,following this simple procedure:1. When turned on, the instrument automatically recalls the last program used. Tochange programs, press the program key and enter the program number from theprocedures manual. The instrument displays the program number, parameter, units,and the zero icon.2. Prepare the blank (zero) according to the procedure, place it in the instrument, andpress the zero key. The instrument displays the zero and the read icon. 3. Prepare the sample according to the procedure. (An internal timer is preprogrammed for methods that require a fixed reaction time.Timer duration is automatically displayed for the selected procedure; simply startthe timer at the start of the reaction.) After reacting the sample, place the samplecell in the instrument and press the read key. 4. The instrument displays the result in concentration units. The user can also togglethe ABS %T key to display absorbance or % transmittance. Some results can bedisplayed in alternate chemical forms (e.g., Cr may be displayed as mg/L CrO4 orCr2O7). Scroll through available forms by pressing the CONC key.5. Save the results by pressing the store key. The instrument will store up to 99measurements in an internal, non-volatile memory. Results may be printed ortransferred to a computer at any time using the Data Transfer Adapter.Instrument cap slidesoff and is used as a light shield duringmeasurement.Ergonomically designedinstrument fits comfortablyin the palm of your hand,with all functions easilyaccessible.Large LCD display promptsuser step by step throughprocedures. Separate areas of the display indicate program number, samplenumber, parameter, testresults, units of measure, and other data.All instrument setup andoperation functions areaccessible by the keypad.Following prompts providedon the instrument display, the user selects theappropriate program, zeroesthe instrument, reacts thesample, and reads the results.Up to 99 individualreadings can bestored andrecalled with thetouch of a button.Built-in timer ispreprogrammed formethods requiring afixed reaction timeand can be set by the user.3DR/800 Colorimeters Quick Reference GuideAluminum Aluminon 8012 • • • 2242000Ammonia, Nitrogen Salicylate 8155 • • 2668000Ammonia, Nitrogen (Test ’N Tube), LR Salicylate 10023 • • 2604545Ammonia, Nitrogen (Test ’N Tube), HR Salicylate 10031 • • 2606945Ammonia, Free, Nitrogen Indophenol 10200 • • 2879700Benzotriazole UV Photolysis 8079 • 2141299Bromine DPD 8016 • • • 2105669Bromine (AccuVac) DPD 8016 • • • 2503025Carbohydrazide Iron Reduction 8140 • 2446600Chloramine, Mono, LR Indophenol 10171/10200 • • 2802246Chlorine, Free • DPD 8021 • • • 2105569Chlorine, Free (AccuVac) • DPD 8021 • • • 2502025Chlorine, Free (Test ’N Tube) DPD 10102 • • • 2105545Chlorine, Free, HR • DPD 10069 • • • 1407099Chlorine, Total • DPD 8167 • • • 2105669Chlorine, Total (AccuVac) • DPD 8167 • • • 2503025Chlorine, Total (Test ’N Tube) DPD 10101 • • • 2105645Chlorine, Total, HR • DPD 10070 • • • 1406499Chlorine Demand/Requirement DPD 10223 • • • —Chlorine Dioxide, DPD • DPD/Glycine 10126 • • • 2770900Chlorine Dioxide, DPD (AccuVac) • DPD/Glycine 10126 • • • 2771000Chlorine Dioxide, MR Direct Reading 8345 • —Chromium, Hexavalent • 1,5 Diphenylcarbohydrazide 8023 • 1271099Chromium, Hexavalent (AccuVac) • 1,5 Diphenylcarbohydrazide 8023 • 2505025Chromium, Total Alkaline Hypobromite Oxidation 8024 • 2242500COD, LR • Dichromate 8000 • 2125825COD, HR • Dichromate 8000 • • 2125925COD, HR+ Dichromate 8000 • • 2415925COD Manganese III 10067 • • • 2623425Copper, LR Porphyrin 8143 • 2603300Copper • Bicinchoninate 8506 • 2105869Copper (AccuVac) Bicinchoninate 8026 • 2504025Cyanide Pyridine-Pyrazalone 8027 • • 2430200Cyanuric Acid Turbidimetric 8139 • • • 246066DEHA (Diethylhydroxylamine) Iron Reduction 8140 • 2446600Detergents (Surfactants) Crystal Violet 8028 • • 2446800Dissolved Oxygen (AccuVac), LR Indigo Carmine 8316 • • 2501025Dissolved Oxygen (AccuVac), HR HRDO 8166 • • • 2515025Erythorbic Acid (Isoascorbic Acid) Iron Reduction 8140 • 2446600Fluoride, Arsenic Free SPADNS 2 10225 • • 2947549Fluoride, Arsenic Free (AccuVac) SPADNS 2 10225 • • 2527025Fluoride SPADNS 8029 • • 44449Fluoride (AccuVac) SPADNS 8029 • • 2506025Hardness, Ca & Mg Calmagite Colorimetric 8030 • • • 2319900Hydrazine p-Dimethylaminobenzaldehyde 8141 • 179032Hydrazine (AccuVac) p-Dimethylaminobenzaldehyde 8141 • 2524025Hydroquinone Iron Reduction 8140 • 2446600Iron FerroZine 8147 • 230166Iron, Ferrous 1,10 Phenanthroline 8146 • • • 103769Iron, Ferrous (AccuVac) 1,10 Phenanthroline 8146 • • • 2514025Iron, Total FerroMo 8365 • • 2544800Iron, Total TPTZ 8112 • • 2608799Iron, Total (AccuVac) TPTZ 8112 • • 2510025Iron, Total • FerroVer 8008 • • • 2105769Iron, Total (AccuVac) • FerroVer 8008 • • • 2507025Isoascorbic Acid (Erythorbic Acid) (ISA) Iron Reduction 8140 • 2446600Manganese, LR PAN 8149 • 2651700ProductTest Method Number NumberDR/890DR/850DR/820EPAParameters marked “EPA” are EPA-approved, accepted, or equivalent for reporting purposes; sample pretreatment may berequired on some procedures.
