The PST 100 spark tester enables fast and economical testing of coatings and linings with thicknesses from 3 to 30 mm.
The device is particularly suitable for checking butt and overlap welds in the plastics and rubber industry, in petrochemical plants and in pipeline construction.
A flexible test probe is included in the scope of delivery. For special applications, additional insulated extension rods and electrodes can be supplied.
In order to guarantee a stable output voltage, excessively large electrodes should be avoided.
A maximum electrode length of 150 mm is recommended for all high-frequency devices.
An optionally available accessory set includes a high-quality transport case and a selection of suitable electrodes for use with the PST spark tester.
