PTS Series - DC High Voltage Test Set and Megohmmeter

0 – 100 kV DC hipot and Megohmmeter PTS-100

in the ?

Features and Benefits

The PTS-100 and PTS-100F 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 10 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 two 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 options.
