The FORENSICS DETECTORS FD-90A-NH3 ammonia detector measures NH3 concentrations from 0 to 100 ppm, with a resolution of 0.1 ppm and a NANO-GAS electrochemical sensor. It uses diffusion sampling without a pump and features adjustable audible, visual, and vibration alarms. A signed and dated calibration certificate is included.
The LCD has a backlight, and the device logs alarms, measures temperature, and supports calibration functions. The 3.7 V, 1,500 mAh Li battery allows more than 48 hours of continuous use. The package includes a belt clip, lanyard, user manual, USB charging cable, and calibration cap.
