Locate and Measure Static Charges

The EFM115 is a convenient electrostatic field meter used to locate and measure static charges and test the balance of air ionizers. Its compact design and four button operation makes it easy to operate and measure static voltages within 20kV (20,000V) at a distance of 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.

The EFM115 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.

Meets periodic test requirements per Compliance Verification ESD TR53 and conforms to ANSI/EOS/ESD (S4.1, S7.1, S12.1, and S2.1) .
