The EZ sc Series Online Analysers offer multiple options to monitor Nitrite in water. Typical applications are drinking water, wastewater, surface water, process water.
The EZ1000sc Series Analysers use colorimetric analysis to measure Nitrite.
- EZ1028sc Nitrite
Standard measuring range:
Nitrite: 1 - 100 µg/L NO₂-N
Options:
- Calibration to 10%, 25% or 50% of standard range (EZ1028 only)
- Internal dilution
- Multiple stream analysis (1-8 streams) reducing cost per sampling point
- Analogue and/or digital outputs for communication
Nitrite and Nitrate can also be measured in combination with Total Nitrogen. For this option please check the EZ7700 Series.
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.
