The HRP-T2000-D is a field-level safety monitoring device that requires no external control system and can operate independently locally. It is designed for gas leak monitoring and audible/visual alarm needs in small and medium-sized industrial sites and single-point risk areas, enabling even non-professional operators to quickly identify risks.
Product Advantages: Plug and play, no external controller required, easy installation, low cost, integrates detection, display, and alarm functions, independent early warning, flexible power supply, multiple installation methods, high reliability, low maintenance cost, and supports customization.
1.Detection and display are separated, so that workers can master the data of hazard sources in real time in safe areas.
2.Super bright screen, tens of meters away can also see the concentration value and alarm status at a glance.
3.The wired connection is stable and reliable, and is not affected by wall occlusion or signal interference, and the data has zero delay.
4.Support local linkage, and can directly control the fan or cut off the valve through the cable when giving an alarm.
5.The installation cost is low, and the remote display function can be easily extended by using the standard communication interface.
HRP-T2000-D independent LCD gas detector
Solution of industrial gas monitoring based on bright liquid crystal display
What is a stand-alone LCD gas detector?
- The displayed information is richer and more intuitive.
- The gas concentration reading is clearer.
- Better visibility in different lighting environments.
- Support more device status and parameter display.
Working principle of HRP-T2000-D
Detection process
- Ambient air continuously enters the sensor detection cavity.
- Gas molecules react with the sensor.
- The sensor converts the gas concentration change into an electrical signal.
- The built-in microprocessor analyzes and processes the signal.
- Real-time concentration data is displayed on the LCD screen.
- Output data through 4-20mA or RS485 Modbus interface.
- When the concentration exceeds the alarm threshold, the equipment automatically starts the acousto-optic alarm and outputs the relay linkage signal.

LED Display Screen(Optional, not required):
This gas concentration monitoring display screen features a dual-color display and connects to the host computer via RS485 protocol. It is primarily used to display real-time concentration data for various gases. The font colors differ between alarm and normal states. Normal state text is blue, while alarm state text is red.
Mounting Bracket(Optional selection):
High-strength metal mounting brackets are specifically designed for mounting gas monitors and actuators, and are typically used for wall-mounted installations.
Calibration Hood(Optional selection):
This is a standard calibration cover specially designed for HIREP series fixed gas detectors, which is used for fast and accurate gas concentration calibration and sensor testing on the equipment site. It has simple structure and good sealing performance, which ensures that the gas can evenly cover the sensor probe during calibration and avoid external interference.
Sampling Tube(Optional):
The sampling tube is made of polytetrafluoroethylene (PTFE), which is resistant to high temperatures and corrosion. It is usually used in conjunction with an external pump to safely and stably deliver the gas to be tested in the environment to the sensor analysis unit. It is suitable for remote sampling, detection in confined spaces, or gas monitoring under complex working conditions.
Explosion-Proof Cable Gland(Optional):
Used for the safe wiring connection of fixed gas detector, alarm host or electrical equipment in explosive environment. Its structure conforms to international explosion-proof standards, ensuring reliable sealing and electrical isolation in flammable and explosive gas environment and preventing accidents caused by sparks or high temperature.
Rain cover(Optional):
Prevents rainwater, dew, and spray water from entering the detector housing, circuitry, and sensor cavity, preventing short circuits due to moisture on the circuit board, reducing rainwater corrosion, and minimizing aging damage to the detector housing and probe caused by ultraviolet radiation. Significantly improves equipment durability, especially suitable for outdoor, open-air, and factory outdoor installation scenarios.
