MASTECH MS5215 High Voltage Digital Insulation Tester

Features
Test Voltage and Insulation Resistance Measurement in Broad Range
Test voltage ranges from 250V to 5kV, in 25V stepped setup, and able for measurement of 5TΩ insulation resistance in maximum.

Supports Various Insulation Judgments 
Able for computation and display of PI (Polarization Index) and DAR (Dielectric Absorption Rate), as well as stepped voltage test (five steps, with voltage and time for each step adjustable), temperature compensation, temperature measurement, leakage current display, and other insulation judgment functions.

Data Storage and Upload Function
Able to manually store 100 data, automatically record 10 groups of data (360 measurement points in maximum for each data group), and automatically record date and time.

Carrying Case
Hard carrying case adaptable to field application is adopted.
Chargeable batteries can be used at the same time
Able to be loaded with 2# batteries and chargeable batteries at the same time, and when capacity of one group of batteries is insufficient, it can be switched to another group for further use.
