MODEL 156A
The Model 156A tests the efficiency of an ionizer’s ion production by timing how long it takes air ions produced to discharge a floating plate that has been pre-charged to either a positive or negative value. The Model 156A also tests the balance between positive and negative air ions by measuring the offset voltage generated on a floating plate due to an imbalance of positive and negative air ions impinging on the plate from the ionizer.
• Large Signal Bandwidth: DC to 10 Hz
• Decay Mode Thresholds:
Start/Stop Voltages Programmable from 1 to ±1000 V in 1 V increments
Start/Stop Accuracy Within ±1 V of programmed voltage
