The fixed dual-gas detector is an industrial-grade safety monitoring device that integrates "independent detection by dual sensors and an integrated body design". It is tailored for high-risk industries where multiple gases coexist. It solves the core pain points of traditional single-gas detectors, such as "repeated installation, complex wiring, and high cost in multi-gas scenarios". It enables 24-hour synchronous and accurate monitoring, hierarchical early warning and centralized management of two gases, and is an efficient solution for multi-gas composite risk protection in industrial sites.

1.Intuitive and visual status: the screen is intelligently switched by red and green colors (normal white/green, alarm red), and the on-site safety status can be instantly judged by color without approaching.
2.Permanent retention of data: High-end models support cyclic storage of dozens of historical alarm records, which is convenient for tracing the time and peak value of faults through the screen.
3.Remote and convenient operation: infrared remote control or magnetic wand operation is supported, and silencing, resetting or parameter setting can be completed in front of the screen without opening the cover, thus ensuring operation safety.
4.Adapt to extreme environment: the screen surface is usually designed with high-strength tempered glass and IP67 seal, which is dustproof, waterproof and corrosion-resistant, and can still be clearly displayed under harsh working conditions.
5.Assist field decision-making: the screen displays the unit, measuring range and sensor life prompt in real time, which helps the inspection personnel to quickly evaluate the health status and detection accuracy of the equipment.

HRP-T2000-F Fixed Dual Gas Detector

Dual Gas Integrated Monitoring Solution for Industrial Safety

HRP-T2000-F fixed dual gas detector is an industrial gas safety monitoring equipment, which can simultaneously detect and continuously monitor two different gases in real time. The equipment adopts the integrated design of dual sensors, and realizes dual gas monitoring in one equipment, which not only improves the safety guarantee ability, but also reduces the installation cost and system deployment complexity.

Supported sensing technologies include:

Electrochemical sensor
Catalytic combustion sensor
Infrared (NDIR) sensor
Oxygen sensor

The system can monitor and process the two detection channels independently at the same time.

Detection process

Ambient air continuously enter that detection cavities of the two sensor;
Gas molecule react with corresponding sensor;
The sensor converts the concentration change into an electrical signal;
The built-in microprocessor analyzes and processes the data of the two channels respectively;
Real-time concentration data is displayed on the LCD screen;
Data is output through 4-20mA or RS485 Modbus RTU interface;
When the concentration of any gas exceeds the alarm threshold, the equipment automatically starts the acousto-optic alarm and outputs the relay linkage signal.

The whole monitoring process runs continuously online, providing all-weather safety guarantee for multi-gas risk industrial environment.
