ERANNTEX Industrial Point Type Combustible Gas Detectors
Brand: ERANNTEX
Specifications
SKU: ERANNTEX Industrial Point Type Combustible Gas Detectors
The Eranntex GTYQ-MIC-300S Industrial point type combustible gas detectors are also available. The detectors are explosion-proof, lightning-proof, anti-static, and reverse-polarity-proof, as well as resistant to EMI/EMC electromagnetic interference and pulse surge current surges. They comply with the national standard GB15322.1-2019 and have passed CPA, explosion-proof, and fire protection product certifications. They support three-wire (or four-wire) 4-20mA signal output and two relay switches, integrate an RS485-RTU bus and a 12V active output (to drive a manipulator/gas valve), and are equipped with on-site audible and visual alarms. They offer optional wired/LAN/Internet/wireless transmission (2 km/5 km/unlimited distance). Wireless transmission supports NB-IOT/4G/LORA/433MHz, and data can be transmitted to a mobile app or cloud platform. A standard 15-meter infrared remote control allows for lid-free operation and supports connection to a computer for real-time monitoring, storage, analysis, and printing of concentration data. An optional external camera allows for simultaneous viewing of video and concentration data, and features automatic zero tracking, drift prevention, and multi-level calibration. High-brightness LED displays or 2.0-inch LCDs are available, and OEM/ODM customization is supported.
