A family of advanced, field proven instruments for high voltage insulation testing, low ohm resistance measurements and verification of protective earthing of power systems.Latest advancements in development of high voltage insulation materials lead to use of modern testing principles.

Technical demands require high performance measuring instruments capable of measuring polarization index (PI), dielectric absorption ratio (DAR), dielectric discharge (DD), time programmable step voltage test, insulation system's capacitance, etc.

Electrical safety verification of machines, portable electrical appliances and switchgear with advanced digital measuring instruments.Complete selection of test instruments for different applications and environments.

Designed to be used in laboratories, workshops, automated production lines and building sites.Advanced, processor backed-up design enables time-efficient and simple measurements.

Complete range of digital power quality measuring instruments for 1- and 3-phase electric supply systems. Metrel power quality analysers are proven tools for expert designers of filtering systems, power correction equipment, over voltage protection and UPS systems.

Wide range of testing possibilities are supported: voltage sags and swells, resonant states, high neutral conductor currents in 3-phase systems, asymmetry, transients, etc.

Structured cabling network testing in accordance with EN50173, ISO/IEC 11801 and other similar standards. Rapid growth of structured cabling IT networks governs that LAN systems are built and tested in accordance with standards like EN50173, ISO/IEC11801 or similar.

Metrel offers a complete selection of high quality LAN testers for verification of copper cabling networks up to CAT 6 (ClassE).

Universal handheld instruments for the measurement, logging and analysing parameters specific for indoor environments are designed to provide flexibility, versatility and convenience to most demanding of professional users.

(Depending on connected probes) they provide the measurement and analyses of temperature (air, black globe and contact), air velocity, relative humidity, illuminance, luminance or act as a sound level meter.
