Overview
The SMART SENSOR AS8906 is a nitrogen dioxide detector that uses a combination of diffusion and pump-suction detection methods to detect the concentration of nitrogen dioxide gas in the environment. The instrument has sound, light and vibration alarm functions, with a range of 0~ 20ppm and a resolution of 1ppm. Electrochemical sensors are used for strong environmental adaptability.
Features
1. Adopt a combination of diffusion and pump-suction detection methods for flexible application.
2. Equipped with sound, light and vibration triple alarm mode, the warning effect is remarkable.
3. Electrochemical sensor with high detection accuracy.
4. Low and high alarm points can be set to meet the needs of different scenarios.
5. Compact size, light weight, easy to carry.
Principle
Electrochemical sensor is built into the detector. When nitrogen dioxide gas in the environment enters the Sensor by diffusion or pumping, a chemical reaction occurs inside the Sensor, generating an electrical signal proportional to the gas concentration. The instrument calculates the current concentration of nitrogen dioxide and displays it by processing the electrical signal.
Applications
Industrial safety, environment monitoring, confined space operations, laboratories
Steps
1. Long press the power button to turn it on.
2. Wait for the instrument to self-test and preheat and stabilize.
3. Place the instrument in the environment to be tested or use a sampling tube for pumping sampling.
4. Observe the real-time concentration reading on the display.
5. When the concentration exceeds the set alarm value, the instrument will issue sound, light and vibration alarms.
6. After use, press the power button for a long time to shut down.
Notice
Do not use in environments beyond the specified temperature and humidity range.
• Avoid strong impact or immersion of the instrument in liquids.
• Periodically calibrated to ensure detection accuracy.
When calling the police, please take appropriate safety measures immediately.
• Please charge in time when the battery is low.
