Fully automatic, easy to use and ideal for use in any laboratory, the T & R PORTATEST is great for measuring the breakdown voltage of insulating liquids.

Supplied with testing voltage of either 60, 80 or 100kV RMS, the PORTATEST is pre-programmed with common national and international testing standards, or gives the user free reign over testing with up to ten freely programmable user testing sequences. Additional functions such as single breakdown tests, a short test program for fast condition evaluation, voltage withstand test and step tests are also possible with this instrument.

When testing, every individual oil sample inserted into the unit is automatically marked with a serial number or with a unique number set by the user. By using the tester's built-in printer, a detailed report of what happened to the sample can be instantly produced after successful testing. These printouts include the date, time, sample number, individual breakdown values, average value and standard deviation.
