Overview
BH-90-NO is a Portable single Gas detector of BOSEAN brand. It adopts 8-bit micro-control technology, which has the characteristics of fast Response speed, high Measurement accuracy, good Stability and Repeatability, and simple operation. Compact size, with high waterproof performance, built-in 1500mA rechargeable lithium battery, super long standby, equipped with 12864 point array LCD screen to display gas concentration and historical alarm data, and supports Data storage function. Suitable for explosion-proof, toxic gas leakage rescue and other places to effectively prevent poisoning accidents and ensure the safety of staff.
Features
1. Adopt mainstream 8-bit micro-control technology, Fast Response, High Measurement accuracy, Stability and Repeatability; 2. Compact size, with high waterproof performance, adapt to harsh environment; 3. Built-in 1500mA large-capacity rechargeable lithium battery, long standby; 4. Equipped with 12864 point array LCD screen, clearly display gas concentration and historical alarm data; 5. Support Data storage function, can view historical alarm data; 6. Bring your own flashlight, convenient for dark environment operation; 7. Support more than 30 kinds of Sensors, flexible configuration, can customize gas; 8. Alarm mode variety, including sound, light and vibration; 9. With password protection function and factory reset function.
Principle
Electrochemical sensor is used to detect gas concentration by diffusion Sampling method. When the gas diffuses to the Sensor, the electrochemistry reaction generates a signal, which is processed by the microcontroller to display the concentration value in real time on the display screen, and alarm by means of sound, light and vibration.
Applications
Explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels
Standards
Explosion-proof mark: Exib IIB T3 Gb, Measurement certificate number: No. 01000158
Steps
1. Power on: press the power button to start the device; 2. Check the power: ensure that the battery is sufficient and charge if necessary; 3. Select the gas type: select the detection gas according to the configuration; 4. Start detection: place the device in the environment to be tested and wait for the reading to be stable; 5. View data: read real-time concentration and historical alarm records through the display screen; 6. Alarm processing: when the concentration exceeds the limit, the device will alarm through sound, light and vibration, and take safety measures in time; 7. Shut down: turn off the power after use.
Notice
* Working ambient temperature range is -20 ℃~ 50 ℃, avoid using beyond this range; * Environmental humidity is 0-95% RH, non-condensing, if Humidity is greater than 90% RH need to be equipped with filtrate drying cylinder; * Sensor life is 2 years, regular inspection and replacement; * Charging time is 4h~ 6h, using original charger; * Equipment Protection Rating is IP65, but need to avoid long-term immersion; * Alarm point is set to low report 50ppm, high report 150ppm, do not modify at will; * With password protection function, default password 8888, it is recommended to modify regularly; * Support to restore factory settings, backup important data before operation; * In In the dark environment, you can use your own flashlight to assist the operation; * Device weight is about 130g, light to carry, but need to prevent fall damage.
