Environmental quality monitoring equipment

TVOC online monitor XDB-TVOC01

First, TVOC online monitor introduction:

This instrument is mainly used for real-time monitoring of TVOC gas at the organic gas discharge port. PID (photoionization) detector is mainly used as the core component. It is a highly sensitive and widely applicable detector that can detect ppb level organic gas. Real-time detection of data transfer via built-in wireless transmission unit (optional).

Second, TVOC online monitor function:

It is mainly used for online detection of TVOC and other gases, and has the advantages of fast response, high measurement accuracy, good stability and repeatability. Equipped with efficient sampling pump can run continuously for a long time; The built-in gas pretreatment unit can dust and dehumidify the gas.

Four, TVOC online monitor principle:

Using an advanced photoionization sensor (PID), it uses an ultraviolet lamp (UV) as a light source to ionize organic molecules into positive and negative ions (ionization) that can be detected by the detector, thus detecting the gas concentration. PID sensor is used as the main detector in this instrument.
