Model SA-220NH
Non-Hazardous Gas Detector
The SA-220NH is a fixed gas detector built for non-hazardous ambient-air applications. It pairs a full-color TFT display with plug-and-play SA2 smart sensor modules, so the detector automatically reads gas type, sensitivity range, and serial number at startup. ABS or aluminum housing options, a magnetic interface, and optional Bluetooth configuration through the OpCheck app make it a practical choice for commercial and light industrial installations where hazardous-area certification is not required.
