The fixed dust detector is an industrial-grade online monitoring device that uses laser scattering technology. It is specially designed for high-risk industries with dust explosion risks and occupational health hazards. It solves the core pain points of traditional dust monitoring such as "low accuracy, slow response and poor environmental adaptability". It can achieve 24-hour continuous and accurate monitoring of dust concentration, graded early warning of exceeding threshold and remote data traceability. It is an essential core device for industrial safety production, occupational health protection and environmental compliance.

1.Ensure the health and safety of personnel
By monitoring the concentration of dust and harmful gases (such as CO and HS) in the air in real time, the equipment can give an alarm immediately when the concentration exceeds the standard. This can effectively prevent the occurrence of occupational diseases such as pneumoconiosis, and avoid fire and explosion accidents caused by high concentration of combustible dust or gas, and provide vital safety guarantee for field personnel.
2.Realizes real-time continuous monitoring.
Different from the traditional portable or manual sampling detection, the fixed dust gas detector can provide uninterrupted monitoring for 7x24 hours. This continuous data flow can help managers find abnormal concentration changes in time and provide reliable and dynamic basis for production process control and safety management.
3.Quick response, convenient installation and maintenance
The equipment is in direct contact with the measured medium, which avoids sampling delay and has extremely fast response speed, and the typical response time can reach 1-3 seconds. At the same time, many modern detectors adopt plug-in or modular design, which does not need complicated sampling pipeline system during installation, and supports plug-and-play and automatic calibration of sensors, greatly reducing the difficulty and cost of installation and maintenance.
4.Adapt to harsh industrial environment
Specially designed for harsh working conditions, with strong environmental adaptability. Many models have high-grade explosion-proof certification (such as Exd IIC T6) and protection grade (such as IP66/IP67), which can withstand harsh environments such as high temperature, high pressure, high humidity and strong corrosion, and ensure long-term stable operation in steel, chemical, mining and other industries.
5.Intelligent management and data traceability
Modern detectors integrate a wealth of intelligent functions. They are usually equipped with data recording and storage functions, and support uploading data to the monitoring platform through RS485, 4-20mA or wireless. Managers can remotely view real-time data, analyze historical trends and receive alarm information, thus realizing intelligent safety management from passive response to active prevention.

  • LED-Display-Screen

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

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

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

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

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

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.
