Overview
The SMART SENSOR AS8421 Gas detector is a Portable handheld gas detection instrument, mainly used to detect the leakage concentration of oxygen, carbon monoxide, hydrogen sulfide and combustible gases in the environment. The device uses an electrochemistry-based gas Sensor, which can monitor multiple gases simultaneously and alarm by sound and light, and is suitable for on-site safety monitoring in multiple working environments.
Features
It can simultaneously detect four gases: oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S) and combustible gas (Ex).
Sensors based on electrochemistry can last up to two years.
3. Equipped with dual alarm functions of sound and light, the alarm sound can reach 80 decibels, and the alarm value can be set.
4. Response Time and Recovery Time are both less than 50 seconds, and the response is fast.
5. The body is light and portable, the weight is only 200 grams, and the size is 120.5 * 64.5 * 38.3mm.
6. Powered by a 3.7V lithium battery, with strong battery life.
7. Strong environmental adaptability, can work normally at temperatures of -10~ 50 ° C and humidity of 15~ 95% RH.
Principle
The gas detector mainly uses the gas Sensor of electrochemistry principle to detect the composition and concentration of specific gases in the environment. The Sensor reacts with the target gas to generate electrical signals proportional to the gas concentration, and the instrument processes these signals to display the gas concentration value. When the detected gas concentration exceeds the preset alarm value, the instrument will trigger the sound and light alarm system.
Applications
Industrial safety monitoring, confined space operation, environment emergency testing, Petrochemicals, mining, municipal fire protection
Standards

Steps
The information does not provide specific operation steps.
Notice
• Do not use under conditions beyond the operating Ambient Temperature (-10~ 50 ℃) or Humidity (15~ 95% RH) range.
• Pay attention to the service life of the Sensor (two years), and calibrate and maintain it regularly to ensure detection accuracy.
The alarm value can be set according to actual needs, please set it reasonably to ensure that the safety warning is effective.
• Use the designated 3.7V lithium battery for power supply to ensure the normal operation of the device.
Instruments are precision electronic equipment, please avoid severe impact or contact with corrosive substances.
