HRP-B1000-D is high-end personal protective equipment that integrates the simultaneous detection of multiple toxic, flammable, and oxygen-deficient gases. Specifically designed for workers in high-risk industries, they solve the problem of rapid early warning and comprehensive safety protection against multi-gas leaks in complex environments, making them core equipment for confined space operations and emergency rescue. They are widely used in complex and high-risk locations such as emergency rescue, equipment maintenance, and gas supply maintenance to achieve simultaneous detection of multiple gases.
1.Multi-gas synchronous monitoring: it can be flexibly configured to detect combustible gas, oxygen, carbon monoxide, hydrogen sulfide and other gases at the same time to meet the needs of different high-risk environments.
2.Specific gas detection: for specific industries, such as chemical industry and refrigeration, there are special models for detecting dichloromethane and halogen gas, which have high sensitivity and strong anti-interference ability.
3.Pump-suction sampling: Some models have built-in sampling pumps, which can be used to remotely sample and detect hard-to-reach areas (such as the inside of pipelines and storage tanks) through probe pipes, thus expanding the detection range.
Portable Four-in-One Multi-Gas Detector
Product Overview
Portable four-in-one multi-gas detector is a personal gas monitoring device specially designed for industrial safety, which can detect four dangerous gases at the same time. Common combinations include combustible gas (LEL), oxygen (O), carbon monoxide (CO) and hydrogen sulfide (HS), which provide comprehensive protection for workers and avoid safety risks such as toxic gas poisoning, hypoxia, oxygen enrichment and explosion.
The equipment adopts advanced sensor technology and has the functions of real-time monitoring, multiple alarms and data recording, which can continuously monitor the change of ambient gas concentration and give an alarm in time when a dangerous situation occurs. The product is small in size, easy to carry and easy to operate. It is widely used in oil and gas, petrochemical, mining, sewage treatment, fire rescue, confined space operation and other industrial fields, and is an important equipment to ensure the safety of personnel.
Principle of Operation
The detector adopts natural diffusion sampling method to continuously monitor the surrounding air environment. The target gas enters the detection area of the sensor through diffusion, and each sensor independently measures the concentration of the corresponding gas.
The collected signal is converted into accurate concentration data after analysis and calculation by the internal microprocessor, and displayed on the LCD screen in real time.
When the concentration of any gas exceeds the preset alarm value, or the oxygen concentration exceeds the safe range, the equipment will immediately start the triple alarm system of sound, light and vibration to remind the staff to take protective measures in time to reduce the safety risk.
According to different application requirements, the detector can be configured as follows:
- Electrochemical sensor (oxygen, toxic gas)
- Catalytic combustion sensor (combustible gas)
- Infrared sensor (hydrocarbon gas, carbon dioxide)
- PID photoionization sensor (volatile organic compound VOC)
