Description

The digital insulation tester model MD10KVx is TENTECH's cutting edge insulation analyzer equipment and it is one of the most complete and sophisticated available in the international market. A software allows for further analysis of tests results, including features such as graphical representation and automatic report generation. Its proven technology provides safe, reliable and accurate measurements of insulation resistances up to 10 TΩ, with 4 pre-selected test voltages, 500 V - 1 kV - 5 kV - 10 kV. Other test voltages may be selected in steps of 25 V, 100 V or 500 V.

A state-of-the-art microprocessor controls the equipment operation and enables the incorporation of advanced features which make measurements easier: auto-range selection, 4000 readings memory, AC/DC voltmeter, automatic measurement of absorption index and polarization index, leakage current and capacitance measurement, timer enabling programming of test duration, configurable pass-fail test, step voltage test, real time clock and calendar. Built-in chronometer, indicating elapsed time, in minutes and seconds, since the test started, up to 90 minutes.

Measured values are transmitted through the USB interface and are printed in the built-in printer as a registration of the performed test. Furthermore, the measured values are stored in a non-volatile internal memory. Up to 4000 measured values may be stored, to be transferred afterward to a computer running the T-Logger program. This software allows a further analysis of the test results, including a graphical representation and automatic report generation. The real time clock and calendar, and the sequential test number, facilitates the identification of each test, and the organization of a predictive maintenance system by trend analysis. The MD10KVx has a Bluetooth interface that allows remote control of it through a Android device with TENTECH's app. With it you can take the photos of the objects under test and the GPS coordinates of each. It also allows you to record voice comments for each measurement.

The MD10KVx is powered by a rechargeable LFP battery. The cabinet is strong and lightweight, easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the megohmmeter supplies very reliable and accurate measurements both in laboratory and out in the field.
