nh3 Vacuum for testing

2018-2-14The vacuum pump is of a dry piston design and is easy to maintain for continuous instrument use. Also available is a non-vacuum model which is suitable for sample gas mixtures with low or consistent levels of CO2 and H2O, such as dilute Constant Volume Sampling (CVS) engine or vehicle exhaust measurement or off-road dry NOx testing
