PID gas detector capable of low level VOC detection
The PID gas detector is capable of detecting low concentrations of VOCs
For gases and vapors that cannot be detected by PID gas detectors, they include radioactive gases (Rm), air (N2, O2, CO2, H2O), common toxic gases (such as CO, SO2), natural gas (methane), acidic gases (such as HCI, HF, HNO3), fluorine gas, ozone, etc.
The PID gas detector is capable of detecting extremely low concentrations of volatile organic compounds with high accuracy, and can meet the quantitative detection of low concentrations of benzene. It is a non-destructive testing instrument
The PID gas detector is capable of detecting low concentrations of VOCs
The calibration of a gas detector is based on the corresponding ion current of a known gas with a known concentration. The instrument response of other gases is related to their own properties, and a reading of 10ppm indicates that the instrument produces the same ion current as the 10ppm calibration gas. The actual concentration of other gases that obtain this reading may be higher or lower than this value. Since PID readings are always related to the calibration gas, this reading should be expressed in ppm units related to the calibration gas, rather than directly using the actual measured concentration value, unless the detected pollutant is the same as the calibration gas or the instrument reading has been calibrated. Usually, PID is calibrated using isobutene because among the VOCs detectable by PID, the sensor's response sensitivity to isobutene is at an average level, making it relatively easy to obtain
The PID gas detector is capable of detecting low concentrations of VOCs
The PID gas detector is mainly a PID or photoionization gas sensor, which can detect extremely low concentrations of volatile organic compounds and other toxic gases. Especially for the sensitive detection of VOCs, which are harmful substances in gases, effective monitoring of them plays an important role.
The use of PID photoionization sensors in gas detection instruments ensures the accuracy and precision of measurement data, and can measure VOCs or other toxic gases ranging from 0.1 to 2000 ppm. PID is a highly sensitive wide range detector, which can be seen as a "low concentration LEL detector"
