Description

Insulation Tester PCE-ITM 20

The isolation multimeter is a combined multimeter and insulation tester /

Test voltage up to 1000 V / Large LCD display / Temperature measurement / Frequency measurement / Internal memory / CAT IV 600 V / IP67 / Wireless USB

This insulation tester PCE-ITM 20 combines a versatile multimeter with an insulation tester. In addition to the usual measured quantities such as voltage, current and resistance, this insulation tester PCE-ITM 20 is also equipped with frequency and capacitance measurement. A thermocouple included in the delivery can also be used to measure the temperature. Automatic range selection (Autorange) allows fast and safe operation with the insulation tester, while the large backlit LCD display ensures good readability.

The highlight of this isolation multimeter is the integrated insulation tester. With test voltages of up to 1000 V, insulation resistances of up to 5000 MΩ (5 GΩ) are measured. Likewise, the insulation tester can directly measure the PI and DAR values. Thus, it is quickly possible to make a statement about the insulation value of the DUT with the help of the insulation tester.

In addition, this insulation tester has an internal memory. This gives you the opportunity to recall the stored measured values for subsequent analysis on the display and to transfer the measured values via the wireless USB interface from the insulation tester to a PC.
