Overview
BH-90A-CL2 is a Portable single Gas detector produced by BOSEAN brand, specially designed to detect chlorine (CL2). The instrument adopts mainstream 8-bit micro-control technology, with the characteristics of fast Response speed, high Measurement accuracy, Stability and Repeatability. The fuselage is compact, easy to operate, and has IP65 protection level of high waterproof performance, which can adapt to harsh working environments. Using high-strength ABS material, equipped with sound, light and vibration three-level alarm functions, safe and reliable, and high and low alarm values can be set. Built-in 3.7V rechargeable lithium battery, long battery life.

8. High and low alarm values can be set as required.
9. Supports more than 30 types of Sensors, and can be flexibly configured or customized according to customer needs Gas detection type.
Principle
The Portable Gas detector uses the diffusion Sampling method, and the target gas enters the instrument through natural diffusion. The instrument has a special sensor for chlorine (CL2). When the gas comes into contact with the Sensor, the corresponding electrochemistry or physical signal changes will be generated. The signal is collected and processed by the microcontroller (MCU) inside the instrument. After calculation by the algorithm, the gas concentration value is displayed on the 1.77 inch high definition screen in real time. When the detection concentration exceeds the preset high or low alarm point, the instrument will immediately trigger sound, light and vibration alarms.
Applications
Chemical industry, petroleum and petrochemical, sewage treatment, environment monitoring, metallurgy and smelting, municipal pipe network, emergency rescue, laboratory, confined space operation
Standards
GB3836.1-2010、GB3836.4-2010、GB15322.3-2003、JJG693-2011、JJG365-2008、JJG695-2003、JJG915-2008
Steps
1. Power on: Press the power button for a long time to start the instrument and wait for the self-test to complete.
2. Calibrate: According to the service cycle or requirements, use standard gas for zero point and range calibrating (please refer to the manual for specific calibrating steps).
3. Settings: According to needs, enter the menu through the instrument button to set the high and low alarm values.
4. Detection: Carry the instrument to the environment to be tested, ensure that the Sensor part is exposed to the air, and wait for the reading to be stable.
5. Reading: Observe the real-time gas concentration value displayed on the screen.
6. Alarm Response: When the instrument emits sound, light and vibration alarm, take corresponding safety measures immediately.
7. Data viewing: The stored alarm records can be viewed through the instrument menu (support 1000 sets).
8. Shutdown: Long press the power button to turn off the instrument, or automatically enter sleep mode when not in use.
9. Charging: When the power is insufficient, use the matching charger to charge the instrument, and the Charging time is less than 5 hours.
Notice
• It is recommended to calibrate the instrument before it is used for the first time or after it has been idle for a long time.
• Do not use under conditions exceeding the working Ambient Temperature (-20~ 50 ℃) and Humidity (0~ 95% RH non-condensation).
• Avoid severe impact or drop of the instrument to prevent damage to the Sensor and internal components.
It is forbidden to use it in an environment containing strong corrosion gas for a long time to avoid damage to the Sensor.
When calling the police, evacuate to a safe area immediately and identify the cause.
• Please use the original charger to charge and ensure a safe charging environment.
• Sensors have a lifespan of about 2 years and should be replaced when they expire or their performance decreases.
• The instrument is designed to be explosion-proof (Exib IIB T3 Gb), but should still be avoided in hazardous locations beyond the Explosion-proof level.
• Do not disassemble or modify the instrument yourself.
• Regularly check whether the Appearance and function of the instrument are normal.
