Honeywell MST Sensors NH3 Version SE 9602-6704 offers an advanced solution for monitoring ammonia gas concentrations. This electrochemical sensor, designed for precision, operates using an amperometric principle where the target gas diffuses through a gas-permeable membrane. The sensor then undergoes an electrochemical reaction that produces a current proportional to the gas concentration, ensuring accurate measurements.

With a standard range of 0 to 100 ppm and a maximum range of 200 ppm, this sensor is essential for various industrial applications. It is particularly suitable for environments where ammonia detection is critical, providing users with reliable performance.

The device features a sensitivity of 140 nA/ppm, ensuring that even low concentrations can be detected promptly, with a response time of t50 < 20 seconds and t90 < 60 seconds based on a 5-minute exposure time.
