944i
lets you measure four electrical safety test parameters from a single test connection

Depend on Vitrek's 944i for all of your programmable or manually operated High Voltage Hipot tester needs for testing electrical safety compliance, earth ground continuity, ground fault, insulation resistance, insulation resistance dielectric breakdown, and arc detection tests.
Vitrek's 944i Hipot Tester combines AC dielectric strength testing (AC Hipot) with DC dielectric strength testing (DC Hipot), Insulation Resistance (HV IR) and a low Ohmic Earth Continuity measurement all in one feature-rich automated instrument. This compact dielectric tester lets you measure four electrical safety test parameters from a single test connection-all with the touch of a button.
Our 944i delivers top performance and versatility for manufacturing tests, product safety engineering, component evaluation, as well as research and development applications. Most hipot testers lack the sensitivity to accurately detect low leakage current levels.  The 944i uses dynamic ranging to provide leakage readings down to 2μA full scale with 1nano-amp resolution.
When it comes to overall dielectric performance - You'll find that the multi-function 944i is loaded with features that even the larger more expensive dedicated testers don't offer. Powerful features including automatic calibration, built-in diagnostics, internal "watchdog" safety monitor, user memory for up to 100 test routines, arc detection and available interface package with IEEE-488.2, RS232 and direct test results printout capability.

The intelligent choice for operator safety
At Vitrek, operator safety is not just a concern, it is a relentless commitment. So we engineered the 944i with a high-impact injection molded front-end with no exposed metal parts to present a potential user shock hazard. We put in an internal "watchdog" safety monitor which automatically shuts down the output in the event of an inadvertent disconnect. And the Vitrek 944i boasts an impressive user programmable "Arc Detection" circuit, capable of shutting down the high voltage system within microseconds.
For added peace of mind the onboard diagnostics of the 944i execute a complete check of all safety systems every time you power up.
