Caution

Do not use for Acid gases such as Cl2, ClO2, HCl, HF, HCN, NH3, NO2, SO2 and others since the PPM gases are absorbed by the tubing, moisture and various wetted parts slowing or completely eliminating response to the target gas. Do not attempt to use below freezing without heat tracing and a means to keep the system above 32? F (0? C). Excessive condensation will occur when sampling from a higher to a lower temperature.
