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
