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
Figure 1 . The single wavelength
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
User-entered calibration on page 21.
