Tera Ohm

TeraOhm

5 kV Automated Insulation Resistance Tester

Model TeraOhm

  • Ultra high Insulation Resistance measurement up to 5TΩ
  • Polarization Index (PI) measurement with programmable timer
  • Voltage, Frequency and Capacitance measurement Storage of 1000 test results in memory, that can be downloaded to a PC
  • Large, backlit LCD display

Description

The TeraOhm is an ultra high range insulation resistance testing instrument. With an output voltage of up to 5000 volts DC the TeraOhm will measure up to 5T (5,000,000 Meg ).

The test voltage can be selected in increments of 50 volts.The duration of the test can be set by the operator. At the end to the test period, the sample is automatically discharged and the insulation resistance is indicated on the display.

Polarization Index tests can also be automatically conducted. At the end of the ten minute period, PI is automatically calculated and up to 1000 results can be stored in the instrument. These results can easily be recalled or can be transferred to a PC using the optional windows software TeraLink+.

The instrument can also be used to measure capacitance up to 50 uF, voltage up to 600 VAC or VDC, and frequency.

The standard instrument is supplied with rechargeable batteries, a calibration certificate and a soft sided carrying case. Batteries recharge using a “ built-in” charger.
