The Hach Phosphate Pocket Colorimeter II Filter Photometer is a true go-anywhere instrument. It is lightweight, battery operated, and suitable for extended field work or quick, on-the-spot process monitoring. It allows user calibrations, offering the capability for creating user-defined calibration curves or performing a standard adjust.
The instrument comes factory programmed, and no manual calibration is ever required. Simply zero the instrument with a blank, insert the reacted sample, and read the result. The Range Indicator icon on the display indicates either the instrument range or the parameter being tested. Record the ten most recent data points with time stamp - no need to record results manually.
The Pocket Colorimeter II offers accuracy and reproducibility comparable to expensive lab instruments, but is designed for a long working life in harsh conditions. A long-lasting LED is used as the light source, and low power requirements assure long battery life.
