This equipment is mainly used for sampling the release of harmful substances in decorative materials such as artificial boards and their products, wooden furniture, carpets, carpet liners, and adhesives for carpets. This product can detect formaldehyde emissions from artificial boards within 4 hours, and has the characteristics of high detection accuracy, fast speed, and strong anti-interference ability.
EN717-2:1995 "Determination of formaldehyde release from artificial boards - Gas analysis method for determining formaldehyde release"
ISO 12460-3-2008 Wood-based panels - Determination of formaldehyde release - Part 3: Gas analysis method
NF B51-272-2-1995 Wood-based artificial boards - Determination of formaldehyde release - Gas analysis method
A. Intelligent temperature control inside the testing cabin is achieved through a constant temperature water bath.
B. Using a touch screen to control the entire system; It is possible to set the on/off time, sampling time, adjust the working temperature, switch between automatic and manual operation modes, and the frequency of data collection.
C. This equipment consists of a clean air supply system, a temperature control system, and a gas sampling control system, and has functions such as water shortage alarm, leakage alarm, fault recording, and historical data export
D. After washing and drying, ensure that the humidity entering the testing chamber is less than 3%.

Place a test sample with a certain exposed area in a testing room where the temperature, airflow, and pressure are controlled within the specified range. Formaldehyde is released from this test sample and mixed with the air in the testing room. Samples are taken in a timed sequence using a sampler. The mixed gas is continuously extracted from the testing room and absorbed through an absorption bottle containing distilled water. The formaldehyde concentration is then determined by spectrophotometry. Calculated in milligrams of formaldehyde released per square meter per hour.
