NH3 ammonia sensor INS-TR-NH3-3XX

for water treatmentfor industrial gas safety monitoringfor industrial process gas monitoring

Overview

The INS-TR-NH3-3XX is an ammonia (NH3) transmitter designed for accurate and reliable detection of ammonia concentrations in industrial, agricultural and technical environments. It enables continuous monitoring of NH3 to protect personnel, secure installations and maintain air quality in sensitive areas.

Applications

Well suited to industrial refrigeration systems, food processing plants, livestock facilities, water treatment stations and industrial sites that require permanent ammonia monitoring.
