HK-7200A Two-Wire LED Toxic Gas Detector, two-wire 4-20 mA (CAT#: STEM-AL-4173-ZJF)

HK-7200A Two-Wire LED Toxic Gas Detector is designed for fixed monitoring and alarm control of combustible or toxic gases. The device applies electrochemical detection with the configured gas sensor or input channels. The documented operating or measurement range is two-wire 4-20 mA. The controller or local display presents concentration, operating status, and alarm information. Current, relay, and digital communication outputs support connection to external control systems where specified. Programmable alarm thresholds distinguish normal, warning, and fault conditions. The enclosure, wiring arrangement, and protection rating suit the stated fixed installation environment. Operating temperature and humidity limits define the approved ambient conditions. The system supports continuous gas monitoring within the documented sensor and channel configuration.
