Air impurities detector is condensation proof - and gives high accuracy over wide concn. range of organic impurities

摘要

An appts. for measuring the concn. of org. air impurities contains a high-sensitivity, condensation-proof, flame ionisation detector giving a signal proportional to the concn. of impurities, and/or contains temp. -compensated circuit components which indicate the readings logarithmically, after amplication.
