The MI1000e general purposes insulation tester is a truly portable equipment suitable to measure insulation resistances using test voltages up to 1 kV. It employs high-reliable, state-of-the-art technology for accurate measurements of insulation resistances up to 200 GΩ with two test voltages: 500 V and 1,000 V. Readings are performed through an easy-to-read analog indicator having a broad scale.
Many experienced technicians consider that insulation measurements are best performed with analog instruments, because they get useful information from the pointer displacement along the time. This equipment is specially indicated for that people, because it is a true analog, simple to use, cost effective, insulation resistance tester.
Insulation of low voltage in electrical systems, transformers, motors, cables, electromedical equipment and installations, distribution networks, etc., the measurement are easily performed with great reliability, using this instrument.
In order to maximize the operator's safety, this equipment was made within a plastic cabinet of high breakdown strength. A light indicator warns about dangerous voltages presence both in the equipment and in the element under testing, and switches-off automatically when the discharge process has finished. This instrument has a GUARD terminal that allows to remove the effects of parasitic resistances and surface currents on the isolation resistances to be measured.
Due to it strong and lightweight cabinet, it’s easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the insulation tester supplies very reliable and accurate measurements both in laboratory and out in the field.
