Overview
The BH-90A-H2 is a Portable single Gas detector from the BOSEAN brand, specially designed to detect hydrogen (H2). The instrument adopts mainstream 8-bit micro-control technology, which has the characteristics of fast Response, high Measurement accuracy, good Stability and Repeatability, and simple operation. The fuselage is compact, made of high-strength ABS material, and has IP65 protection level, which can withstand the test of harsh environment. It is equipped with two-stage triple alarm (sound, light, vibration), high and low alarm values can be set, and built-in large-capacity rechargeable lithium battery, long battery life.
Features
1. Adopt Industrial Sensor to Ensure Reliability.
2. The mainstream 8-bit micro-control technology is applied, and the performance is stable.
3. The fuselage is compact, easy to operate, and easy to carry and use.
4. With IP65 protection level, it is highly waterproof and dustproof.
5. Fast Response and High Sensitivity.
6. Long standby time, Continuous Operating Time can reach more than 10 hours.
7. Supports more than 30 types of Sensors, which can be flexibly configured or customized as needed.
Principle
The Portable Gas detector uses the diffusion Sampling method, where the target gas in the environment naturally diffuses into the Sensor gas chamber through the ventilation hole of the instrument shell. The Sensor (for hydrogen as the principle of electrochemistry) reacts with the gas to generate an electrical signal proportional to the gas concentration. The signal is processed by the instrument's microcontroller, and finally the gas concentration value is displayed in real time 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, metallurgy and mining, environment protection, municipal gas, emergency rescue, power electronics, laboratory research and other places where hydrogen leakage exists or may occur.
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 the data: Read the real-time gas concentration value through the display screen.
5. Alarm Response: When the instrument emits sound, light and vibration alarm, take immediate safety measures.
6. Shutdown: Long press the power button to turn off the instrument.
7. Charging: When the power is insufficient, use the matching charger to charge the instrument.
Notice
• Please read the instructions carefully before use and make sure the instrument is calibrated.
• Do not use in environments exceeding the specified temperature (-20~ 50 ℃) and Humidity (0~ 95% RH non-condensation).
• Avoid severe impact or drop of the instrument to prevent damage to the Sensor.
When calling the police, evacuate to a safe area immediately and identify the cause.
• Do not disassemble or modify the instrument yourself.
• Sensors have a lifespan of approximately 2 years and need to be calibrated or replaced periodically to ensure accuracy.
• Please use the original charger when charging and ensure the safety of the environment.
• The explosion-proof mark of the instrument is Exib IIB T3 Gb, please use it in the specified explosion-proof area.
