Features/Customers Benefit

Customized measuring ranges for calibration of the H2O2-Sensor

Two measuring ranges: 1 to 50 mg/l and 40 to 500 mg/l = ppm Unique photometer for H2O2 with these measuring ranges

Simple handling and simultaneously high accuracy Simplier than extensive preparation of standard solutions More accurate, than rapid colorometric test sticks Faster than titration

DEV-based Method (Deutsche Einheitsverfahren H 15) reliable, approved method with less interferences long term stable dye; so different reading time is not critical
