Overview
The SMART SENSOR AR820 is a household formaldehyde Gas detector. Electrochemical sensor is used to detect the concentration of formaldehyde gas in the environment. The instrument has a measurement range of 0~ 5PPM and a resolution of 0.01PPM. It has a dual sound and light alarm function. Portable design, powered by 3 AA batteries.
Features
1. Sensor using electrochemistry principle to detect formaldehyde gas.
2. The measurement range is 0~ 5PPM, and the resolution is 0.01PPM.
3. Equipped with dual alarm functions of sound and light.
4. Response Time is less than 30 seconds and Recovery Time is less than 50 seconds.
5. Built-in temperature measurement function.
6. Portable design, weight only 110g, powered by 3 AA batteries.
7. Strong environmental adaptability, temperature 0~ 50 ℃, humidity 10~ 95% RH.
Principle
The detector mainly uses a gas Sensor to detect the type and concentration of gases present in the environment. The Sensor with electrochemistry principle is specifically used to detect the composition and content of formaldehyde gas. When the Sensor comes into contact with formaldehyde gas in the environment, it will generate a corresponding electrical signal, and the instrument will process the signal to display the gas concentration value.
Applications
Household environment formaldehyde concentration detection
Steps
1. Load three 1.5V AA batteries.
2. Boot in an environment of 0~ 50 ° C and 10~ 95% RH.
3. Place the instrument in the test environment.
4. Wait for Sensor Response (< 30 seconds) and read the formaldehyde concentration on the display.
5. When the concentration exceeds the standard, the instrument will issue a sound and light alarm.
Notice
• Instrument intrinsic error is +/- 10%, measurement results are for reference only.
• Please ensure that it is used in a working environment of 0~ 50 ° C and 10~ 95% RH.
• The sensor response time is less than 30 seconds, and the recovery time is less than 50 seconds. Please give enough detection time.
Do not use in environments beyond the specified temperature and humidity range, so as not to affect the measurement accuracy or damage the instrument.
• Regularly check the battery level to ensure that the instrument is working properly.
• This product is a household testing instrument and is not suitable for accurate Measurement in professional or industrial fields.
