Product Details

Product Introduction

Formaldehyde testing chamberMainly used for detecting the emission of pollutants, including formaldehyde and VOCs, from materials and products such as small furniture, building panels, paint coatings, and small equipment. The same applies to detecting the emission of pollutants from products such as automotive parts and plastic tracks. This product has obtained the national invention license, license number 2015102462743.

1. Extremely low background concentration;

2. Temperature and humidity display and control;

3. Ensure uniform temperature to prevent condensation;

4. The wind speed of the mixing fan can be adjusted to meet the requirements of the testing space wind speed;

5. The amount of clean air can be precisely adjusted;

6. Extremely low work noise creates a quiet workspace;

7. Parameters such as temperature and humidity, clean air supply volume, and pressure difference can be downloaded remotely;

8. Computer monitors the operation of multiple devices.

Formaldehyde testing chamberThe testing principle:

The process of testing pollutant release in an environmental chamber can be summarized as follows: placing materials and products or their samples in the testing chamber, adjusting the environmental conditions such as temperature, relative humidity, and air replacement rate in the chamber as needed; Sampling at the exhaust outlet or inside the environmental chamber; Using appropriate methods to analyze gas samples, identify the main pollutants and their concentration changes over time; Then determine the release rate and release characteristics of the material and product based on the measured concentration.
