The Hach DR/800 Series Colorimeter is a microprocessor-controlled, LED-sourced filter photometer suitable for colorimetric testing in the laboratory or the field. The instrument is precalibrated for common colorimetric measurements and includes convenient calibration capability for user-entered and future Hach methods.
Key Features
- Test results are displayed in concentration, absorbance, or percent transmittance
- Automatic wavelength selection and ranging in the preprogrammed parameters
- Data storage and recall for datalogging in the field or laboratory
- Conversion of results to alternate forms for many parameters (i.e., PO4, P2O5, P)
- Reagent Blank Correction and Standard Adjust features may be used to compensate for lot-to-lot variations in reagents
- Icon prompts displayed during testing
- A built-in timer to monitor specific reaction times called for in the test procedures; appropriate times are programmed into the calibration data for specific tests; the timer also can be used manually by the operator independent of the stored methods
- IR output for RS232 interface capability allows an external printer or computer to interface with the colorimeter
- Entry of user-entered methods or new Hach methods
- Error signals for procedural or instrument troubleshooting
- The colorimeter operates on battery power and holds 4 AA-size alkaline dry cells (batteries supplied) that power the instrument for at least 6 months
