Product Description

Fixed Multi Gas Leak Detector For Composite Gas LEL H2S CO O2 Ex Gas Detection

>>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.
