Description

Ohm Metrics Pocket Static Field Meter:

EFM115

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 inter­face makes it easy to operate. The EFM115 measures
static voltages within ±20kV (20,000V) at a distance of
1".

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
makes the EFM115 the ideal meter for static audits, and
periodic verification of ionizers and meets periodic test
requirements per Compliance Verification ESD TR53 and
conforms to ANSI/EOS/ESD (S4.1, S7.1, S12.1, S2.1).

Ohm Metrics test and measurement products, from

Transforming Technologies, are useful, reliable tools for
characterizing and identifying the electrical resistance of
materials and the performance of personal grounding
products.

 All Ohm Metrics products are designed to support

ESDA Compliance Verification TR53.

 All Ohm Metrics products can be calibrated.

 All Ohm Metrics test and measurement products are

warranted for 1 full year.
