The model 300 uses large, high-contrast, alpha/numeric LED displays for easy reading at any vieweing angle, even in high ambient lighting conditions. Individual LED’s, provide additional operation status during testing and setup. Single-button operation of manual +decay, -decay and balance ensures simple, easy operation. Balance tests record ±peaks and average reading. Each test can be customized in setup for stop trip levels and test duration. An automated set of tests can be initiated with a single button depress.

Operation and setup can be done via a USB port and PC software in addition to the front panel buttons. Test results can also be retreived for automatic or manual test.
Real time analysis of ionizers can be done via the analog output.
