Details: The most professional ammonia gas detector by FORENSICS DETECTORS. Equipped with electrochemical sensors and comes factory-calibrated. The detection range of NH3 is 0 - 100ppm within 30 seconds at an accuracy of +/- 5% full-scale. Comes factory NIST calibrated from Los Angeles, CA. The detector has a DC3.7V Li-battery 1500mAh that allows for up to 24 hours of continuous use. Includes advanced features such as temperature detection, alarm recording, alarm setting, backlight high-resolution LCD, calibration features, and others. Ammonia is a toxic gas that requires continuous detection, particularly in occupational spaces. NH3 is used in farm fertilizers and commercial refrigeration, water purification, treatment facilities, chemical plants, high-technology manufacturing, and household cleaners. These devices are primarily used to detector ammonia from livestock, pig & poultry operations, chemical plants, and cold storage lockers. 

Included: Gas detector, belt clip, sling, English manual, USB charging cable, calibration cover, and USA NIST calibration certificate.
