Overview
The SMART SENSOR AS8909 is a hydrogen detector that uses diffusion and pump-suction detection methods to detect hydrogen (H2) gas. It has a range of 0~ 1000ppm and a resolution of 1ppm. It has triple alarm functions of sound, light and vibration, and is suitable for a variety of working environments.
Features
1. Optical inspection Sensor principle, high detection accuracy.
2. It has both diffusion and pump-suction detection methods to meet the needs of different scenarios.
3. With low alarm point and high alarm point, alarm value can be set, alarm mode includes sound, light, vibration.
4. Powered by 3.7V lithium battery, the fuselage is light and the weight is about 200g, which is easy to carry.
5. Strong environmental adaptability, temperature range is -10~ 50 ℃, humidity range is 15~ 95% RH.
Principle
The hydrogen detector works based on the principle of Optical inspection Sensor. When hydrogen gas in the environment enters the instrument through diffusion or built-in pump, the Optical inspection element in the Sensor will react with the hydrogen in a specific way, resulting in changes in the Optical inspection signal. The instrument detects and analyzes the changes in these Optical inspection signals to calculate the concentration of hydrogen in the environment, and triggers sound, light and vibration alarms when the preset alarm value is reached.
Applications
Chemical production, oil and gas, electric power, laboratory research, environment monitoring, fire safety

Steps
1. Check whether the Appearance of the instrument is in good condition and whether the power is sufficient.
2. Turn it on in clean air and wait for the instrument to self-check and stabilize.
3. According to the testing requirements, choose the diffusion type (natural contact) or the pump suction type (active extraction) for testing.
4. Place the instrument Probe in the test area and observe the hydrogen concentration reading on the display.
5. If the concentration exceeds the preset alarm value, the instrument will automatically trigger the alarm, and corresponding safety measures need to be taken immediately.
6. After use, turn off the power and store it properly.
Notice
Do not use in an environment that exceeds the specified temperature (-10~ 50 ° C) or humidity (15~ 95% RH).
• Avoid strong impact or drop of the instrument to prevent damage to the internal Sensor.
• Periodically calibrate to ensure the accuracy of test data.
The alarm value should be set reasonably according to specific safety regulations.
When the alarm is triggered, evacuate to a safe area immediately and identify the cause.
• Please use the designated charger to charge the battery.
• The instrument is not suitable for use in environments where there is a potential explosion hazard, unless it has the corresponding explosion protection certification (the information does not mention the explosion protection level).
