MEASURING MACHINE AND METHOD FOR DETECTING THE CONTENT OF OIL, HYDROCARBONS, AND OXIDIZABLE GASES IN AIR OR COMPRESSED AIR

摘要

The invention relates to a measuring machine for detecting the content of oil, hydrocarbons, and oxidizable gases in air or compressed air. Said measuring machine comprises an air or compressed air connection and a flow limiter (D) connected thereto, and a catalyst (K) connected to the flow limiter (D). A photoionization detector (S) is connected to the catalyst (K), wherein switchable means (90, 72) are provided for directing the air or compressed air over the catalyst (K) and past the same directly to the photoionization detector (S).
