Air Ion TesterThe tester can read up to 1999. Any readings higher than this, the tester reflect just the digit 1 or -1 (for negative ion readings).

 Test Range: Ion test range between 1 × 104 to 1999 × 104 ions/cc

Note: The ion tester is not meant for very precise readings. The reading does not stop at an exact value. Rather, it indicates the range of negative ions present at the point of measurement.
