HCl Gas Detector Fixed Hydrogen Chloride Corrosive Gas Leak Alarm Industrial Safety System Honeywell Sensor
>>Overview
Our company's online gas detector utilizes original imported smart gas sensors, serving as an intelligent, high-performance instrument capable of continuous online monitoring of combustible gases, toxic/hazardous gases, and specialty gases.
Featuring an integrated flameproof enclosure structure, the detector delivers high sensitivity and precision. Through connection to a GDS gas alarm controller and monitoring management software, it enables real-time concentration display on computers. Additionally, by incorporating an optional wireless module, real-time monitoring data and alarm status can be transmitted to safety control centers.
>>Features
◆ Original imported high-performance sensors ensure high measurement accuracy, excellent repeatability, and extended service life.
◆ Independent AD chip effectively resists electromagnetic interference and filters disruptive wavelengths.
◆ Instrument supports dual displays (LED digital tube & LCD), compliant with the latest national standards.
◆ Multiple selectable units: mg/m³, ppm, VOL%, LEL%, etc.
◆ AI-based temperature/humidity compensation algorithm minimizes measurement errors.
◆ Automatic protection against high-concentration gas impact; features factory reset function to prevent misoperation.
◆ Infrared remote control enables operation without opening the enclosure – simple and convenient.
◆ Configurable outputs: 3-wire 4-20mA, RS485, relay contacts; supports HART protocol.
◆ IP66 protection rating for harsh industrial environments.
◆ Triple explosion-proof certification (Ex db ib IIC T6 Gb / Ex ib tb IIIC T80°C Db) – Certified by National Explosion-proof Electrical Testing Center.
