Please-mail ATEquip.com for Product Availability or a Price and Delivery Quotation. Thank you.

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), High Voltage Insulation Resistance Withstand (HV IR ) with Arc Detection as well as 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.
The Vitrek 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.

If your product requires one of these labels. . .
Demand that the Vitrek 944i label is on your Dielectric Analyzer. Only Vitrek minimizes overall test time and maximizes system reliability by combining four dielectric test functions in one unit.
It would hardly seem possible that a slow dielectric tester could back-up an entire production line. Yet with today's imposing 100% dielectric inspection requirements, the antiquated manual hipot tester is often the manufacturing bottleneck. Imagine the consequences of the tester breaking down or worse yet passing a defective product.
Just a few good reasons why each 944i Multi-function Dielectric Analyzer is equipped with two high performance microprocessors - to speed testing throughput and to execute exhaustive onboard diagnostics. Simply put, the Vitrek 944i provides the fastest, most accurate and reliable test results available. And it does it for a surprisingly modest price.

Powerful Yet Easy to Use
We've harnessed the power of the microprocessor to make this dynamic instrument simple and easy to operate. Specifically, the extensive use of menu prompting walks you through the test setup. Built-in user memory allows you to store, recall and edit up to 100 different test programs. All test parameters are fully user selectable - no hidden switches or pots to hamper operation.
The result is a clean, streamlined panel design that demands noticeably less effort to operate - and the unrivaled power to execute customized test routines at the touch of a button.
Capacity to Excel
With its full 35mA sourcing capability, the Vitrek 944i possesses the horsepower required to drive today's capacitively-filtered circuits - loads which the 10mA to 25mA units just can't handle. Yet, what sets the 944i apart from the rest is its ability to discriminate between in-phase and out-of-phase leakage currents.
This advanced feature enables you to measure the resistive current associated with insulation breakdown, the reactive component or the combination of both.
Vitrek Service & Support: Finest in the Instrument Industry
At Vitrek, we manufacture automated test instruments that are human engineered for friendly easy operation. But that's not where our commitment stops. We back you up with a worldwide network of Vitrek support centers. And we provide support by phone or email for any need or questions that may arise.
This all adds up to one point - you'll enjoy doing business with Vitrek. Our service technicians, application engineers and customer service satisfaction people just wouldn't have it any other way.
