low cost voc density sensor pricing

Cost. Electrochemical VOC sensors. 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.

  • VOC Sensors and Monitors - Volatile Organic Compounds

    Targeted VOC measurements are useful in controlled environments (e.g. labs, research) where the target compound is used and process control or health and safety risks are required. To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration.

  • Accurately Measuring Volatile Organic Compounds (VOC’s

    most VOC molecules, with the exception of low molecular weight VOC’s, will break up into free electrons and positively charged ions, a process called ionization. This ionized gas is electrically charged and produces an electric current. The ion current is collected by the sensor, ampli˛ed and converted to a reading either in ppb or µg/m³.
