The EZ sc Series Online Analysers offer an option to monitor Hydrogen Peroxide (H₂O₂) in water. Typical applications are drinking water, surface water, process water.
The EZ1022sc Analysers use colorimetric analysis to measure Hydrogen Peroxide.
Standard measuring range: 5 - 500 µg/L H₂O₂
Options:
- Calibration to 25% or 50% of standard range
- Internal dilution
- Multiple stream analysis (1-8 streams) reducing cost per sampling point
- Analogue and/or digital outputs for communication
Some applications may require the use of a sampling/filtration or a external dilution system for sample preconditioning. For this option please check the EZ Series Sample Preconditioning page.
