PPO-Elektroniikka Oy

PPO-Elektroniikka Oy specializes in safety technology. We have been solving our customers’ technical challenges and problems since 1981. All of our own solutions are related to improving safety and minimizing and preventing damage.

Initially, we aimed to develop a system to improve electrical safety in the operating rooms. The first insulation monitoring device, MEV-3, was launched at the beginning of 1982. Our MEV-3 revealed a big problem in hospitals; many more devices had electrical current leakages than expected. Therefore, the authorities decided in 1983 that this kind of equipment became mandatory in Finnish operating rooms.

MEV® Insulation Monitoring System

Our MEV-insulation monitoring system has saved lives and protected valuable equipment in Finnish hospitals since 1982. The electrical current leakage is a real danger to the staff and patients; it can cause a fatal electric shock without any visible signs. No operation will be performed in Finnish operating rooms if insulation monitoring is not used.

Wellbeing services counties in Finland and private hospitals use the MEV insulation monitoring system. Our fifth-generation MEV-8 has been in production since 2020. We have developed MEV-8 in cooperation with hospital engineers – the new-generation equipment meets all international regulatory acts and technical standards.


In addition to MEV®, we have other technology solutions:
