Wireless composite gas detectorIt is an intelligent safety device that integrates multi gas detection, wireless transmission, and real-time warning functions, widely used in industrial safety, emergency rescue, environmental monitoring, and other fields. Its core advantage lies in the use of a built-in high-precision sensor array and wireless communication module to achieve synchronous detection and remote data transmission of toxic and harmful gases, flammable gases, and volatile organic compounds (VOCs), providing key technical support for safety control in hazardous environments.
This device is based on a composite technology of electrochemical sensors (detecting toxic gases such as CO and SO ₂), catalytic combustion sensors (detecting flammable gases), and photoionization sensors (PID, detecting VOCs). It can simultaneously monitor 5-6 gas parameters. Some models (such as AreaRAE Pro) also integrate meteorological sensors to obtain real-time data on wind speed, wind direction, temperature and humidity, and assist in analyzing gas diffusion trends. Its wireless transmission function is achieved through LoRa, Wi Fi, or Mesh networks, supporting real-time bidirectional data exchange with the monitoring center. One computer can manage 64 devices simultaneously, forming a monitoring network covering a large area.
Wireless composite gas detectorPreparation before use:
1. Inspection and Charging
Appearance inspection: Check if the instrument casing is intact, without cracks or damage. Check if the air intake/sensor window is clean and unobstructed (can be cleaned with a soft bristled brush or a balloon).
Power check: Check the battery level when turned on. Ensure that the battery is fully charged. If the battery is low, use the matching charger to fully charge it. It is recommended to fully charge before each use.
Charging: Connect the charger to the instrument charging interface and turn on the power. The indicator light usually displays (such as red constantly on/flashing) during charging, and turns green or goes out when fully charged.
2. Confirm sensor status
Check if the sensor is within its validity period. Expired sensors may experience decreased sensitivity or failure.
For new instruments or instruments that have not been used for a long time, it may be necessary to preheat (Warm up) to allow the sensor to stabilize (usually 1-3 minutes).
3. Function self-test (startup self-test)
Press the power button, and the instrument will automatically perform a Power On Self Test.
Observation:
Display screen: Are all icons and backlighting functioning properly.
Indicator light (LED): whether the red, yellow, and green lights flash in sequence.
Buzzer/Speaker: Does it emit a "beep" sound or voice prompt.
Vibration motor: whether it vibrates.
After passing the self-test, the instrument enters normal detection mode.
