Two chamber formaldehyde emission test chamber EN 717-2 ISO 12460-3 NF B51-272-2
This equipment 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.
Model: HJ-FET-01
Features
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%.
Working principles
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.
