The Fixed Multi-Gas Detector is a multi-gas simultaneous monitoring and safety warning device specifically designed for fixed operational environments such as industrial production, warehousing, chemical industrial parks, and underground utility tunnels. Its core functionality integrates multiple high-precision gas sensors to continuously monitor two or more target gases in the environment (e.g., combustible methane, toxic carbon monoxide/hydrogen sulfide, oxygen in oxygen-deficient/oxygen-enriched environments, or sulfur dioxide/nitrogen oxides in industrial exhaust) . This enables real-time detection of abnormal gas concentrations and immediate safety alerts. hydrogen sulfide, oxygen in oxygen-deficient/oxygen-enriched environments, or sulfur dioxide/nitrogen oxides in industrial exhaust), enabling real-time monitoring. It promptly detects abnormal gas concentration changes and triggers alarms, preventing safety incidents like poisoning, explosions, or suffocation caused by gas leaks at their source.
Fixed Multi-Gas Detector Features:
Simultaneously detects 1 to 6 gases with freely switchable units.
Diverse communication methods.
Enables real-time monitoring via wired/wireless remote transmission or network communication; Simultaneous output of standard RS485 bus (Modbus-RTU) and 4-20mA standard signals; Optional frequency output (200-1000Hz), Hart protocol signals, 1-5V output, wireless transmission (2-5km or unlimited range); Compatible with secondary instruments, data acquisition modules, PLCs, and DCS systems; capable of driving related equipment. Optional MIC2000 controller enables simultaneous monitoring of up to 1000 detectors.
Infrared Remote Control.
Standard infrared remote control enables one-touch operation via function keys, allowing cover-free operation in hazardous environments. Functions include: alarm point modification, concentration calibration, zero calibration, mute, and factory reset.
Rich Human-Machine Interface.
2.5-inch high-definition color screen displays real-time concentration, alarms, time, temperature, humidity, and storage information; Menu interface employs high-definition simulated graphics to display functional names for each menu.
Large-capacity data storage with multiple storage modes.
Standard 100,000-data-point storage capacity; optional SD card storage supports real-time logging, scheduled logging, or alarm-level data logging only. Data can be viewed/deleted locally or uploaded via RS485 interface for computer analysis or printing.
High-temperature gas detection (optional).
Optional high-temperature sampling cooling filter handle or high-temperature/high-humidity pre-treatment system enables detection of flue gas up to 1300°C. Customization available for other temperature ranges.
Three switchable display modes.
Simultaneously displays multiple gas concentrations; large-font cyclic display of single-channel gas concentration; real-time curve display.
Graphical display shows gas concentration trends over time as curves.
● Data recovery function allows partial or full restoration, eliminating concerns over accidental operations.
● High-precision temperature and humidity measurement (optional).
● Multiple alarm methods with multi-directional visual/audible alerts. Includes: 3 sets of relay switch outputs, audible/visual alarms, and display visual alerts. Alarm types: concentration alarm, low voltage alarm, fault alarm.
