EZ Series Nitrite Analyzers 水中線上硝酸鹽/亞硝酸鹽自動分析儀
The EZ Series Online Analyzers offer multiple options to monitor Nitrite in water. Typical applications are drinking water, wastewater, surface water, process water.

The EZ1000 Series Analyzers use colorimetric analysis to measure Nitrite.
- EZ1028 Nitrite
- EZ1301 Nitrite & Nitrate
Standard measuring range:
Nitrite: 1 - 100 µg/L NO₂-N
Nitrate: 0.2 - 10 mg/L NO₃-N

- 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.
