SKU: ERANNTEX Fixed Carbon Monoxide Alarm
The Eranntex GTYQ-MIC-500S-CO-A Fixed carbon monoxide alarm features explosion-proof, lightning-proof, anti-static, and reverse polarity protection designs, as well as immunity to EMI, EMC, and pulse surge currents. It complies with the latest national standards and holds the CPA measuring instrument production license and explosion-proof certification. It supports three- or four-wire 4-20mA standard signal output, voltage output, and two relay switches. It also features a standard RS485 bus output (RTU format) and on-site audible and visual alarms. It offers optional wired, LAN, internet, and wireless transmission (2 km, 5 km, or unlimited distances), including 433, GPRS, Wi-Fi, and other methods. The standard infrared remote control allows for operation without opening the cover in hazardous locations, with a range of 15 meters. It also supports computer communication, allowing real-time monitoring of probe concentrations via a host computer, and data storage, analysis, and printing. Units can be switched between, and the alarm automatically tracks the zero point to prevent drift. It offers multi-level calibration and supports OEM and ODM customization.
