Test Method:
The chemical agents are added to the mixing chamber as a liquid using syringe pump. The gas is first vaporized and mixed with 30 ℃, 70% R.H. 30L./min clear air. Then this mixed gas flows into the test box. In this test, Multi-gas Monitor Type 1302, Brael & Kjaer, Denmark (non-disperse IR) is used to monitor the concentration of the gas.
Remark:
The minimum breakthrough time is intended only for laboratory tests under standardized conditions. It does not give an indication of the possible service time in practical use. Possible service times can differ from the breakthrough times determined according to this standard in both directions positive or negative depending on the conditions of use. Please review the Frequently Asked Questions and Terms and Conditions if you have question using the PSM. Or contact us, we will assist you and respond as soon as possible.
