Formaldehyde test specimens were pretreated in a balanced constant temperature and humidity chamber

Product details

Purpose and scope of use

Formaldehyde test specimen balance pretreatment constant temperature and humidity chamber is the test equipment specially produced for gb18580-2017, GB17657-2013 standard plate sample 15 days of pretreatment requirements, the equipment has a device with multiple environmental chambers, can be at the same time for a number of different samples of the specimen balance pretreatment, (The number of environmental cabin can be customized according to the site and customer needs), the number of test cabin has 4 cabin, 6 cabin, 12 cabin four standard models.

Formaldehyde test specimen balance pretreatment constant temperature and humidity chamber provides a separate test space, can eliminate formaldehyde test specimen release formaldehyde pollution to affect the test results, greatly improve the test accuracy. The multi-compartment configuration makes it possible to carry out cyclic test, which greatly improves the test efficiency.

The specimen was placed at 23±1℃, relative humidity (50 ±3) % for (15±2) d, the distance between the specimens was at least 25mm, so that the free circulation on the surface of all specimens, the indoor air replacement rate of constant temperature and humidity was at least once an hour, and the mass concentration of formaldehyde in the indoor air could not exceed 0.10mg/m3
