>>Overview

Equipped with original imported intelligent gas sensors, this is a high-performance intelligent detection instrument capable of continuous online monitoring of multiple gases. The detector features an integral explosion-proof structure with high sensitivity and precision. Real-time gas concentration data can be displayed on a computer through a gas alarm controller and monitoring software. Additionally, optional wireless modules enable real-time transmission of monitoring data and alarm statuses to safety control centers. It is widely applicable across industries such as petroleum/petrochemicals, metallurgy, environmental protection, gas, fire safety, municipal services, chemical engineering, shipbuilding, power generation, process control, wastewater treatment, and emergency rescue monitoring.

 
>>Features
◆ Original imported high-performance sensors with high measurement accuracy, excellent repeatability, and long service life.
◆ 16-bit AD chip and 4-layer PCB design ensure enhanced weak signal processing and superior anti-interference capabilities.
◆ Dashboard-style display interface with clear, elegant readings and user-friendly design details.
◆ Multiple unit options: mg/m³, ppm, VOL, and LEL.
◆ Embedded 32-bit low-power processor paired with proprietary signal processing algorithms for fast response speed and high stability.
◆ Auto-protection against high-concentration gas impact, factory reset function, and misoperation prevention.
◆ Built-in infrared remote control for easy operation without opening the housing.
◆ Configurable outputs: three-wire 4–20mA, RS485 signal, and relay output.
◆ Dual cable entry ports for convenient on-site installation.
◆ Robust mechanical design: Gas chamber made of high-grade aluminum alloy profile ensures wear-resistant, corrosion-resistant performance in harsh industrial environments. Scientifically optimized gas chamber design guarantees real-time monitoring accuracy.
◆ Explosion-proof certification: Exd II CT6, certified by the National Explosion-Proof Electrical Product Testing Center.
