Operation
Model 287B performs manual or automatic decay and balance tests for periodic verifiction of ionization equipment. It then stores the results and averaged decay times for up to ten manual tests and up to ten complete automatic test sequences. Temperature and relative humidity are displayed real-time and recorded with the test data.
All instrument functions are controlled by four pushbuttons
In DECAY mode a built-in high voltage generator charges the plate to over 1050 volts. During testing the plate will discharge toward zero in the presence of ionization. The elapsed time of decay between 1000 volts and 100 volts is displayed.
In the BALANCE mode, isolated plate voltage, test duration and + and - peak voltages are displayed.
Self-tests include battery check and tests for functional errors.
Now take the mystery out of ionizer testing
Test your AC or DC room ionizers, laminar flow, overhead or benchtop ionizers or ionized compressed gas systems as simply as pushing a button.
Optional Model 287/22C 6” x 6” Plate Adapter
This optional adapter enables the model IPA 287B to perform very comparibly to charged plate monitors designed to ESD Association standard No. 3.
Calibration:
Monroe Electronics instruments are factory-calibrated prior to shipment. Recalibration should be performed annually, or more frequently if specified by contract or company policy. Your instrument should also be recalibrated any time it has been repaired or tampered with. We will be happy to perform the calibration for you or refer you to one of our Authorized Service Organizations.
