Reliant EMC


more then 30 years of EMC Technology from HILO-TEST

In the 70’s EMC (electromagnetic compatibility) became an important regulatory issue in the USA. The European market also realized the issue of EMC and started to enact it own standards in this time frame.
The founders of HILO-TEST realized the market potential and need for test equipment that would allow manufacturers to test their products to the new EMC standards.
The name of HILO-TEST derives from “high voltage test equipment” and “low current measuring resistors”.
Since its early stages, HILO-TEST influenced the development and progress of EMC technology.
Today HILO-TEST offers the industry’s widest range of standardized EMC equipment, comprising of technically outstanding test instrumentation, such as the compact CE-Tester.
The compact CE-Tester provides test capabilities for Burst, Surge and Mains Simulation and complies with the latest national and international EMC standards.



EMC instrumentation, designed by HILO-TEST, and adapted to individual customer requirements, makes up a substantial portion of HILO-TEST’s production. Its experience, together with the use of up to date production technologies allow HILO-TEST to manufacture prototypes and modifications to existing equipment in very short time.
