Accurate measurement of gases requires gas samples with stable dew points even under harsh ambient conditions.The PKE Models feature a coolingsystem with an aluminum cooling block. Fitted into the blockis a removable high-efficiency heat exchanger made ofstainless steel, DURAN-glass or PVDF.The PKE 5 is designed for moderate ambient and gastemperatures (2.5 lpm at@158°F) and an inlet dew point ofabout 104°F. (approx. 5% vol). For higher ambienttemperatures up to a maximum of 122°F order the PKE 52x.The dew point of 41°F is regulated by an electronic controller.

The temperature (in °F or °C) of the cooling block is shown onan LED-display. The status is indicated by a flashing displaywhich shows high or low temperature and operates together with a relay in fail-safe mod.
