• Exceeds current requirements of ANSI/ESD SP3.3 for Periodic Verification of Air Ionizers
• Test Balance and Decay
• Low Cost / Performance Ratio
• Hand-held, Battery Operated
• Microprocessor Driven
• Built -in Self Test
• Exclusive Monroe Electronics Two-year Warranty
Operation
Model 287B performs manual or automatic decay and balance tests for periodic verifiction 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 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.
Test your AC or DC room ionizers, laminar flow, overhead or benchtop ionizers or ionized compressed gas systems as simply as pushing a button.
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.
