Abstract: Environment temperature can influence the test of Gas Permeability Characteristics of Plastic Film and Sheeting.This article provides PID constant temperature control based on the use of thermoelectric cooling and SCM-MSC1210,which is a new type analog signals processing SCM with such characteristic as high-powered simulation and digital processing ability.This can improve the accuracy of this test.

Key words: gas permeability test; thermoelectric cooling; PID constant temperature control; MSC1210 SCM.;
