The EFM115 meter is a convenient electrostatic field meter used to locate and measure static charges and test the balance of air ionizers

The EFM115 meter can be used to measure low voltages up to 200V in ion balance mode with a built-in charge plate. The combination of field meter and ion balance tester make the EFM115 the ideal meter for static audits, and periodic verification of ionizers. Static voltage measurements are ± 0 ~ ± 1.49 kV in low range, and ± 1.0 ~ ± 20.0 kV in high range. Unit features an LCD display (digital and bar graph).

The compact design and four-button operation make it easy to operate. The EFM115 measures static voltages within ±20kV (20,000V) at a distance of 2.5cm (1"). Results are simultaneously displayed numerically and in bar graph format on an easy-to-read LED screen. Two LED guide ring lights help position the field meter at the right distance from a charged test object.
