Overview
BH-90A-CO is a Portable single Gas detector, using mainstream 8-bit micro-control technology, with fast Response speed, high Measurement accuracy, good Stability and Repeatability, and simple operation. Its small size, IP65 protection level, high-strength ABS material shell, can adapt to harsh working environments. The instrument is equipped with sound, light and vibration triple alarm, high and low alarm values can be set, built-in 3.7V rechargeable lithium battery, long battery life.
Features
1. Industrial Sensor with High Sensitivity.
2. Adopt mainstream 8-bit micro-control technology.
3. The fuselage is compact and easy to operate.
4. IP65 protection level, with high waterproof performance.
5. Long standby time, continuous operation for more than 10 hours (gas can be used for no less than 7 hours).
6. High-strength ABS material, two-stage triple alarm (sound, light, vibration) is not easy to ignore.
7. High and low alarm values can be set.
8. Support more than 30 kinds of Sensors, flexible configuration, can be customized according to customer needs gas.
Principle
The detector uses the diffusion Sampling method, and the gas enters the instrument through natural diffusion. The built-in industrial-grade Electrochemical sensor (for gases such as CO) reacts with the target gas to generate an electrical signal proportional to the gas concentration. The main control unit of the instrument (8-bit microcontroller) processes and calculates the signal, and finally displays the real-time gas concentration value on the display screen. When the concentration exceeds the preset high and low alarm values, the instrument will trigger a triple alarm of sound, light and vibration.
Applications
Petrochemicals, gas transmission and distribution, municipal fire protection, metallurgical smelting, environment monitoring, emergency rescue, industrial safety inspection
Standards
GB3836.1-2010、GB3836.4-2010、GB15322.3-2003、JJG693-2011、JJG365-2008、JJG695-2003、JJG915-2008
Steps
1. Power on: Long press the power button to start the instrument.
2. Self-test: Sensor and system self-test after the instrument is started.
3. Detection: Place the instrument in the environment to be tested and wait for the reading to stabilize.
4. View data: Read real-time gas concentration through the display screen.
5. Alarm Response: When an alarm occurs, take appropriate safety measures according to sound, light and vibration prompts.
6. Shutdown: Press the power button for a long time to turn off the instrument, or wait for it to shut down automatically.
7. Charging: Use the matching charger to charge the built-in lithium battery.
Notice
Make sure the instrument is fully charged before use.
• Do not use in environments exceeding the specified temperature Humidity (-20~ 50 ℃, 0~ 95% RH non-condensation).
• Avoid severe impact or falling of the instrument.
When calling the police, please evacuate to a safe area immediately and identify the cause.
• Sensors have a lifespan of approximately 2 years and need to be calibrated or replaced periodically to ensure accuracy.
• Charging time should be less than 5 hours, please use the original or designated charger.
• This instrument is designed to be explosion-proof (Exib IIB T3 Gb), but it still needs to be used under safety regulations.
• The instrument contains 1000 sets of alarm records, which can be reviewed regularly.
• For the range, resolution and alarm point of the specific gas, please refer to the corresponding parameters of the model.
• If not used for a long time, please turn it on regularly and charge the battery.
