GG-NH3 Ammonia Gas Detector Overview
Finally, one ammonia gas detector sensor is designed to perform in all environments. The intelligently adaptive GG-NH3 goes anywhere.
The GG-NH3 utilises proven electrochemical sensor technology for fast and accurate leak detection. The GGNH3 provides real-time, continuous monitoring of ammonia concentrations, accurately down to 5 ppm, with no false alarms.
Every GG-NH3 sensor comes equipped with an intelligent internal temperature control designed to perform in the harshest areas. The controlled environment provides optimum moisture control for extended cell life. The high-quality injection-moulded polycarbonate enclosure offers excellent chemical corrosion protection and high impact resistance.
The GG-NH3 provides an industry-standard linear 4-20 mA output signal compatible with most gas detection systems and PLCs. The output signal is not affected by drastic temperature variations, such as washdowns or defrost cycles. SAFECELL checks the electrical viability of the electrochemical cell and drops the signal to 0.5 mA when the cell fails or is missing.
