DR/800 Series

The DR/800 Portable Colorimeter Series comes in three models (20, 50, or 90 methods) with automatic wavelength election. Preprogrammed, the DR/800 Series works right out of the box. Use these compact instruments for hand-held analysis, even in rugged environments (designed to meet IP67 standards).     Easy-to-use software offers push-button method selection, automatic wavelength selection and a preprogrammed method timer. Results are displayed immediately, with no countdown. The instrument retains the selected method until the user enters a new method, even after the DR/800 Colorimeter is turned off and then back on at a later time. This allows a series of analyses to be performed for the same parameter without reselecting the method.     Datalogging capability includes push-button record-keeping. Store data in the field for later access, with no delay in testing. The instrument stores up to 99 measurements in internal, non-volatile memory. Data stored includes date/time, parameter, program number, concentration/absorbance/ %T, sample number, and instrument serial number, all of which greatly simplify record-keeping tasks.     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, PO4 and P2O5. Displayed results can be changed from one form to the next at the touch of a button.     User-program feature allows generation of up to 10 custom procedures, with up to 12 data points each, and storage in non-volatile instrument memory for later use.     Advanced software includes the ability to automatically correct for reagent blanks, and the option to fine-tune calibration curves with the standard adjust feature.     Models Include:   DR 820 (tests for 20+ methods)   DR 850 (tests for 50+ methods)   DR 890 (tests for 90+ methods)

Key benefits of the DR/800 Portable Colorimeter Series:    
        
  • Easy-to-use software offers push-button method selection, automatic wavelength selection and a preprogrammed method timer. Results are displayed immediately, with no countdown. The display is very easy to read, and includes result, units and parameter name.    
  • The instrument retains the selected method until a new method is entered, even after the DR/800 Colorimeter is turned off and then back on at a later time. This allows a series of analyses to be performed for the same parameter without reselecting the method.    
  • Datalogging capability includes push-button record-keeping. Store data in the field for later access, with no delay in testing. The instrument stores up to 99 measurements in internal, non-volatile memory. Data stored includes date/time, parameter, program number, concentration/absorbance/ %T, sample number, and instrument serial number, all of which greatly simplify record-keeping tasks.    
  • 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, PO4 and P2O5. Displayed results can be changed from one form 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 non-volatile instrument memory for later use.    
  • Advanced software includes the ability to automatically correct for reagent blanks, and the option to fine-tune calibration curves with the standard adjust feature.    
  • Batteries provide self-contained power for field testing. Nominal battery life is 6 months with standard AA alkaline batteries. Rechargeable alkaline batteries are also available.    
  • The optional Data Transfer Adapter (DTA) fits onto the instrument and accepts data sent from the instrument's infrared light emitting diode (LED) transmitter. The DTA converts data to standard RS232 format and connects directly to a computer or printer. Data can be printed or downloaded at any time--after it is stored in the instrument or while it is being collected.
