Rigel Uni-Therm High Current Electrosurgical Analyzer

The high performance Rigel Uni-Therm electrosurgical analyzer accurately measures the performance of electrosurgical generators including high frequency leakage, high current, power distribution and patient return plate alarm testing.

Compliant with IEC 60601-2-2, the Uni-Therm electrosurgical analyzer is capable of verifying and calibrating all major electrosurgical generators whilst guiding the user through all test procedures automatically and most of all safe.

A unique high power low inductance load bank enables performance testing up to 8 ampere RMS with a duty cycle of up to 100% making the analyzer an extremely versatile test instrument for calibrating and performance testing of conventional and high power electrosurgical generators. The load bank allows testing in a range of 0-5115Ω with a resolution of over 1000 steps providing high detailed power profiles. The Rigel Uni-Therm also advocates safe working practise by providing all necessary resistors within a single enclosure.

Return electrode monitoring capability can be performed both manaully as well as automatic. A high accuracy potentiometer provides testing within 1Ω resolution, ideal when testing alarm settings based on impedance variance.

Product features include onboard memory, test automation, comprehensive data management facilities and a wide range of in-built resistors, while a large full colour screen displays easy-to-follow, step-by-step instructions to ensure the correct connection to the device under test.

Output waveforms can be examined through a built-in scope output which allows for easy confirmation of the desired waveform shape.

The Uni-Therm high performance electrosurgical analyzer forms part of a comprehensive range of high performance specialist biomedical test equipment supplied by Rigel Medical.
