Wavelengths: 420 nm, 520 nm, 560 nm and 610 nm. Dustproof, waterproof, shockproof, and worry free High-value, high-capability field instruments for water quality analysis More Advanced Features that Add Value Accessories Simplify Data Management Easy Quality Control Advanced Features Easy-to-use software offers push-button method selection, automatic wavelength selection and a preprogrammed method timer. Result, units, and parameter name are displayed immediately, with no countdown. The large digit display is very easy to read. The DR/ 800 retains the selected method until a new method is entered, even if it is turned off and then back on. This allows a series of analyses to be performed for the same parameter without reselecting the method. Datalogging capability includes push-button record management. Easily store data in the field for later access, with no delay in testing. The instrument stores up to 99 measurements in an internal, non-volatile memory. Data stored includes date/ time, parameter, program number, concentration/ absorbance/ % T, sample number, and instrument 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, 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 a non-volatile instrument memory for later use. Advanced software includes automatic correction for reagent blanks and the option to fine-tune calibration curves with the standard adjust feature. Batteries provide self-contained power for field-testing.
