Beschreibung
Zusammenfassung:	A photoionization detector sensor equipped with a temperature compensating and output adjustable ultraviolet lamp driver for supplying an alternating current signal to the ultraviolet lamp effective to light the ultraviolet lamp with direct current supplied from both a first variable voltage supply circuit and a second temperature sensitive fixed voltage supply circuit, and method of standardizing output of the photoionization detector sensor by adjusting the voltage supplied to the driver by the first variable voltage supply circuit so that future reported values will more closely approximate actual values.
