INSULATION TESTERS

Insulation Testers have been totally conceived for the use in Industrial environment and are particularly recommended for insulation testing on Motors, Cables, Transformers, High Voltage Insulators and all Electrical Installations which present significant Insulation Values. The instruments are available with NiMh rechargeable cell in Single, Dual, Multi Voltage and Multi Insulation Ranges.

Auto Range Digital Insulation Testers
(Microprocessor based)

Digital Insulation Testers (Microprocessor based) have automatic range selection and resolution & switch over to the next higher range and over range is displayed by infinity. The instrument registers time duration of test voltage applied to material under test and displays current time & date on a 16x2 Digit Alpha Numeric LCD Display. Short circuit current is 1mA. The instrument has excellent accuracy, voltage stability, linearity & auto off management features and is operationally fully safe.

Microprocessor Based 5000 Volts Insulation Analyzer (Model DIT _µp)

Microprocessor controlled programmable insulation analyzer model DIT_µp can be operated in triple mode instrument as a conventional mega ohmmeter, a dielectric absorption ratio (DAR) test set or as a polarization index (PI) test set at 5KV DC and performs all necessary calculations to determine DAR & PI results. The instrument registers time duration of test voltage applied to material under test and displays current time & date on a 16x2 digit alpha numeric LCD display. The instrument has excellent accuracy, voltage stability & linearity and is operationally fully safe. Results can be printed on a built-in printer with date & time for record purpose, This feature allows identifying possible trends that would reveal the gradual deterioration of the insulation.
