Hach DR/2000 Direct Reading Reading Spectrophotometer
Ours looks like the one in the photo.
The Hach DR 2000 Spectrophotometer is a microprocessor-controlled, single-beam instrument suitable for the laboratory or the field.
Features:
The results can be displayed in percent transmittance, absorbance or concentration of the appropriate units of measure. The LCD dot-matrix digital display offers automatic ranging in the pre-programmed parameters, operator-selected languages (a choice of 14), full prompting during testing and error messages for procedural or instrument troubleshooting. A built in timer helps the operator observe specific reaction times called for in the test procedures. R-232 interface capability allows an external printer to be driven by the spectrophotometer, and a 0 to 1-volt analog output is provided for a recorder.
