Product overview

The single wavelength Pocket Colorimeter II instruments are portable
filter photometers used for testing water, treated waters, wastewater,
estuary and seawater. Refer to
models are configured at the factory to measure at a specific
wavelength.
The single wavelength models have two channels in which
measurements can be made. Until a user-prepared calibration curve is
entered, the single wavelength instruments show only a direct readout
of absorbance. To measure concentration, enter a user-prepared
calibration curve. Refer to
