The FORENSICS DETECTORS FD-60-NH3 wall-mounted ammonia detector measures NH3 concentrations from 0 to 100 ppm, using an electrochemical sensor with a resolution of 1 ppm. Sampling is performed by natural diffusion, without a pump, and the sensor is factory-calibrated. It comes with a signed and dated calibration certificate.
Adjustable low and high alarms activate two relays for controlling fans, ventilation systems or other electrical equipment up to 50 W per relay. The alarm includes an LED and buzzer, while the device supports a 4–20 mA analog output and digital logging via RS485 MODBUS.
