Overview
The BH-90A-O3 is a Portable Ozone (O3) Gas detector that uses mainstream 8-bit micro-control technology and features fast Response, High Measurement accuracy, Stability and Repeatability. The instrument is compact and easy to operate. It has IP65 protection and a high-strength ABS shell, which can withstand the test of harsh environments. It uses a two-stage triple alarm (sound, light, vibration) design, which is safe and reliable, and supports high and low alarm value settings.
Features
1. Adopt Industrial Sensors.
2. Adopt mainstream 8-bit micro-control technology.
3. The fuselage is compact and easy to operate.
4. With IP65 protection level, it is highly waterproof.
5. Fast Response and High Sensitivity.
6. Long standby time, working continuously for more than 10 hours.
7. Supports more than 30 types of Sensors, allowing for flexible configuration of gas types as required.
Principle
The Portable Gas detector uses the diffusion Sampling method, in which the target gas in the environment diffuses through the ventilation hole of the instrument housing into the Sensor. The Sensor (electrochemistry or semiconductor principle for ozone) reacts with the gas to generate an electrical signal proportional to the gas concentration. The signal is processed by the built-in 8-bit microcontroller, and finally displays the real-time concentration value on the 1.77-inch high definition screen. When the concentration exceeds the preset high and low alarm point, the instrument triggers a triple alarm of sound, light and vibration.
Applications
Chemical industry, petroleum, gas, metallurgy, electric power, environmental protection, municipal administration, fire protection, emergency rescue, sewage treatment, laboratory

Steps
1. Power on: Long press the power button to start the instrument.
2. Self-test: Sensor and system self-test will be automatically performed 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: View real-time gas concentration through the screen.
5. Alarm handling: When the alarm is triggered, take corresponding safety measures according to the sound, light and vibration prompts.
6. Shutdown: Long press the power button to turn off the instrument.
7. Charging: Use the matching charger to charge the built-in 3.7V lithium battery.
Notice
Please read the instructions carefully before use.
• It is recommended to calibrate the instrument before first use or after long-term idleness.
• Do not use in environments outside the -20~ 50 ℃ Temperature range or 0~ 95% RH (non-condensation) Humidity range.
• Avoid severe impact or falling of the instrument.
• Do not disassemble or modify the instrument yourself.
When calling the police, please evacuate to a safe area immediately and identify the cause.
• Sensors have a lifespan of about 2 years and need to be replaced in time when they expire.
• Please use the original charger when charging. Charging time is less than 5 hours.
• The explosion-proof mark of the instrument is Exib IIB T3 Gb, please use it in the specified explosion-proof area.
• The instrument does not have Data storage function, but can record 1000 sets of alarm records.
