Overview
The BH-90A-CLO2 is a Portable single gas detector designed to detect chlorine dioxide (CLO2) gas. 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 small and sturdy, with IP65 Protection Rating, good waterproof performance, and can adapt to harsh working environments. Equipped with three alarms of sound, light and vibration, it is safe and reliable, and the high and low alarm values can be set freely.
Features
1. Industrial-grade Sensors are used to ensure detection accuracy.
2. Mainstream 8-bit micro-control technology, stable performance.
3. The fuselage is compact and easy to operate.
4. With IP65 protection level, waterproof and dustproof.
5. Fast Response and High Sensitivity.
6. Long standby time, up to 10 hours of continuous operation.
7. High-strength ABS material shell, strong durability.
8. Supports more than 30 types of Sensors, which can be flexibly configured or customized as needed.
Principle
The detector uses the diffusion Sampling method, where the target gas in the environment diffuses into the interior through the air inlet of the instrument. The built-in Electrochemical sensor (for CLO2) reacts with the gas to generate an electrical signal proportional to the gas concentration. The signal is processed by the microcontroller and finally displays the gas concentration value in real time on the display screen. When the concentration exceeds the preset high or low alarm value, the instrument will trigger three alarms of sound, light and vibration.
Applications
Chemical industry, environmental monitoring, water treatment, Food processing, medical and health, laboratory, emergency rescue, 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: Long press the power button to start the instrument.
2. Self-test: Conduct self-test after the instrument is started to observe whether the display screen and alarm functions are normal.
3. Detection: Place the instrument in the environment to be tested and wait for the reading to stabilize.
4. Alarm settings: Set high and low alarm values through the menu (e.g. low report 5ppm, high report 10ppm).
5. Data viewing: You can enter the menu to view historical alarm records (up to 1000 sets).
6. Charging: Charge the built-in lithium battery with the matching charger, and the Charging time is less than 5 hours.
Notice
• Please read the instructions carefully before use to ensure that it is used within the instrument range (0-50ppm) and applicable environment (-20~ 50 ℃, 0~ 95% RH non-condensation).
• Avoid instrument impact or prolonged exposure to extreme environments.
• Periodically calibrated to ensure detection accuracy, Sensor nominal life is 2 years.
When calling the police, appropriate safety measures should be taken immediately and evacuated to a safe area.
• Please use the original charger when charging and ensure the safety of the environment.
• This instrument is designed to be explosion-proof (Exib IIB T3 Gb), but it is still required to comply with relevant safety regulations in hazardous areas.
• When the instrument shows abnormality or malfunction, it should be stopped and a professional should be contacted for maintenance.
