2. Compact size, with high waterproof performance, can withstand the test of harsh environment
3. Built-in 1500mA large-capacity rechargeable lithium battery, long standby
4.12864 point array LCD display technical indicators and gas concentration values, you can view historical alarm data
5. Data storage function
6. Bring your own flashlight for easy operation in dark environment
7. Support more than 30 kinds of Sensors, flexible configuration, can be customized according to customer needs gas
Principle
The detector uses the principle of catalytic combustion Sensor to detect gas concentration by diffusion Sampling method. When the gas concentration reaches the preset alarm point, the alarm is carried out by sound, light and vibration.
Applications
Explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels
Standards
Exib IIB T3 Gb, IP65, Preparation No. 01000158
Steps
1. After booting, the device self-checks and displays real-time gas concentration
2. View technical indicators and gas concentration values through 12864 point array LCD screen
3. Historical alarm data can be queried
4. Use the password protection function (default password 8888) to modify the settings
5. Support factory calibration and parameter setting functions
6. In the dark environment, the flashlight can be turned on to assist the operation
Notice
• Working ambient temperature range -20 ℃~ 50 ℃, Humidity 0-95% RH (non-condensing)
• Humidity greater than 90% RH need to be equipped with filtrate drying cylinder
Sensors have a lifespan of 2 years and require regular maintenance
• Charging time 4h~ 6h to avoid overcharging
• The alarm point is low 50ppm and high 150ppm, please do not modify it at will
• Use the password protection function, the default password is 8888, it is recommended to modify it in time
Equipment Protection Rating is IP65, but extreme conditions still need to be avoided
• weight about 130g (excluding portable Accessories), pay attention to anti-drop when carrying
• Display error ≤ +/- 5% FS, Response Time T < 60s, these parameters need to be considered when using
