How do you choose a VOC sensor? | Engineer Live

Mar 12, 2019· With resolution from 10 to 50ppb, electrochemical cells are low-cost, low-power, compact sensors. Electrochemical sensors need to be optimised for the target VOC because each VOC requires a different ideal bias voltage for best sensitivity. Also, electrochemical cells respond in about 25 seconds, in comparison with one-to-two seconds for PIDs.
