Overview
BH-90M-CO2 is a single gas detector under the BOSEAN brand, belonging to the BH-90M series. The product adopts industrial grade Sensor and micro control technology, with the characteristics of Fast Response, High Accuracy measurement, excellent stability and repeatability. Its design is inspired by pebbles, Appearance is round and small, the shell is made of high-strength engineering plastic and covered with composite anti-skid rubber, with waterproof, dustproof and explosion-proof characteristics. It is detected by natural diffusion, easy to use and maintain, and meets the needs of industrial site safety monitoring for high reliability of equipment.
Features
1. Industrial Sensor and Micro Control Technology, Fast Response, High Measurement Accuracy, Excellent Stability and Repeability.
2. Appearance design is round and small, inspired by pebbles, no edges and corners, strong durability.
3. The shell is made of high-strength engineering plastics and covered with composite anti-skid rubber, providing high strength and good feel.
4. With multiple protection functions such as waterproof, dustproof, and explosion-proof.
5. Sensitivity and repeability are good with natural diffusion detection.
6. Easy to use and maintain, high reliability.
Principle
The gas detector uses natural diffusion for gas detection. Gas enters the instrument through natural diffusion, the built-in industrial-grade Sensor senses the gas concentration, and processes and calculates it through advanced micro-control technology, and finally displays the result on the LCD screen with High Accuracy data. When the detected gas concentration exceeds the preset alarm point, the instrument will issue an alarm through Light Emitting Diode, sound and vibration.
Applications
Petroleum, chemical industry, environmental protection, metallurgy, refining, gas transmission and distribution, agriculture, explosion-proof places, toxic gas leakage rescue, underground pipelines, mines, power plants, tunnels, tunnels
Standards
GB3836.1—2010、GB3836.4—2010、GB12358—2006、GB15322.3—2019、JJG693—2011、JJG365—2008、JJG695—2019、JJG915—2008
Steps
1. Power on: Long press the power button to start the instrument.
2. Self-test: After the instrument is started, a self-test will be carried out to observe whether the display and indicator lights are normal.
3. Detection: Place the instrument in the environment to be tested and wait for the reading to stabilize.
4. Reading: Real-time gas concentration data is read through the LCD screen.
5. Alarm Response: When the sound and light vibration alarm occurs, immediately take safety measures and evacuate.
6. Shutdown: Long press the power button to turn off the instrument.
7. Charging: When the battery is low, use the matching charger to charge the built-in lithium battery, which lasts about 4 to 6 hours.
