UV Digital Nitrite(NO₂⁻) Sensor : TLS-UVNO2
- Reagent-free Measurement
- Real-time, Continuous Monitoring
- High Detection Sensitivity for Trace-level Nitrite Monitoring
- UV Absorbance at Specific Wavelengths(typically ~235 nm)
No reagents required, minimizing operational and maintenance costs.
Supports real-time and continuous in-situ monitoring for reliable water quality control.
High detection sensitivity for low-level nitrite, ideal for aquaculture, drinking water, and environmental monitoring.
Utilizes UV absorbance at a specific wavelength(~235 nm) to ensure accurate measurement and minimize interference from other substances.
