The PRO DIT-925 and PRO DIT-927 series High Voltage Insulation Resistance Testers are intelligent, high-end insulation resistance testers, well-developed by METRAVI. The instruments come with perfect test functions of various insulation resistance parameters and excellent anti-interference ability. They can be used in 220kV Sub-station and have no Corona effect.

The instruments adopt true-colour touchscreens and all test data and battery power are displayed at the same time. The combination of knob switch and button makes the operation very simple. The user need not memorise the operation method, just needs to click the “HELP” on the screen and a pop-up displays the operation method, which effectively guides the user to operate the respective instruments.

The instruments have the function of rapid discharge and automatically monitor the live voltage of the measured object. If voltage exceeds 36V, the test is automatically disallowed in order to protect the instrument and operators effectively. The meters automatically store test results which contain date and time. The touch screen can very convenient to check and analyse the recorded historical data. The fully isolated USB interface uploads the test data to the PC safely.

The instrument is equipped with double insulation and shielding layer test wire and the high voltage rod is equipped with replaceable crocodile clips and hooks, which can be used in various test places. The instruments feature hard double-shell structures, and the meter outer cases have IP65 protection level, which prevents moisture and dust intrusions and collision during transportation and storage, protecting the meters effectively. 

Suitable for insulation resistance testing of cable, motor, generator, transformer, mutual inductor, high voltage switch, arrester and other large equipment.
