Volatile Organic Compound Monitor (PID)

A. Instrument principle

The sample gas is irradiated by a UV lamp, and the organic matter to be tested is ionized into positive and negative ions. The positive and negative ions move towards two stages under the action of an electric field, generating current. The current is amplified by a signal amplifier and output as data. After being monitored, positive and negative ions recombine into the original gas.PIDIt is a non-destructive monitor that does not "burn" or alter the gas being testedPIDThe monitored gas can still be collected for further measurement, and after being monitored, the positive and negative ions recombine into the original gas. PID is a non-destructive monitor that does not "burn" or alter the gas being measured. The gas monitored by PID can still be collected for further measurement.
