Trek PD04002A Series

The ultra-sensitive Trek^® PD04002A makes it the ideal choice in air ionizer monitor applications where small area ion collecting sensors are used to meet the requirement for high accuracy ion balance measurement to levels of less than one volt. The voltage of the charged plate is initialized before discharge time testing. Balance tests, positive discharge tests, and negative discharge tests can be initialized from a remote location through digital command signals. The charged plate voltage can be remotely monitored through a rear panel connection. The Trek^® PD04002A utilizes a new technique that requires less than 0.1 picoamperes of ion field current to achieve full accuracy and stability. Other product designs require up to 2000 times more ion current to be drawn from the ion field to achieve stability.
