Abstract This article describes laboratory tests on photoionization detectors (PIDs) integrated into portable multi-gas detectors, the purpose being to demonstrate the usefulness of these instruments in occupational hygiene. The performance characteristics of these PIDs (sensitivity, linearity, response time, etc.) were determined using a polluted atmosphere generating system. The laboratory test results reveal that these detectors are particularly advantageous for preventing occupational risks, particularly for monitoring pollutant concentration levels and for developing a sampling strategy. However, they cannot perform all the functions normally fulfilled by more sophisticated PIDs, such as exposure profile plotting or installation gas leak detection.
