Model 785 (1-15 Kv) – Portable

For thicker coatings such as coal tars, extruded and tape coatings, the Model 785 has a range of infinite voltage settings from 1,000 to 15,000 volts. This wide range permits you to maintain a steady inspection rate on most types of coatings on most pipe sizes without changing detectors. Pulse voltage output only.

Product Features

INFINITE VOLTAGE SETTING allows you to set the voltage exactly to the level you desire for the coating you are inspecting. Not six settings, not twenty… any setting you desire over the complete range of each detector model. Whatever the pipe size, two inches through sixty inches, you have at your control the exact voltage setting required.

AUTO REGULATED VOLTAGE keeps your voltage constant! Over a range of two inch through sixty inch pipe the detector output voltage automatically adjusts under the working load to the voltage levels you set. Now you can forget compensations for pipe size, or moisture on the pipe – the detectors automatically make these adjustments.

QUICK RELEASE BATTERY easily slips into position with a snap that announces positive contact and a secure lock in position. Two batteries and a universal charger are part of the kit. For continuous service, one battery is kept charging (approx. 8 hours) while the other powers the unit.
