Features and Benefits

The PTS-75, PTS-75F5 and PTS-75F6 are combination high voltage DC proof tester and megohmmeter. Dielectric strength and insulation resistance testing are combined into one instrument saving time, money, size and weight. Equipped with a 5-range current meter scaled 0 – 1 dc microamps for accurate current measurement down to a 10 nanoamp resolution in the x1 range. Using the alternate scale on the current meter allows the PTS Series to double as a Megohmmeter up to 7.5 teraohms, scaled 100-1 megohms, insulation resistance can be taken at any voltage. An accurate 2 range voltmeter rounds out the standard instrumentation. Additional features include ruggedized anti-static and transit protected meters, rugged single piece design with foam padded handles, full-wave bridge rectifier, internal shorting solenoid with discharge resistors, and is CE marked. For other voltage options, please see the rest of our PTS Series which range from 15kV to 600kV DC. See our DBT Series for bench-top
