Rigel Uni-Therm High Current Electrosurgical Analyzer

The new 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.

Bluetooth-enabled technology allows wireless connectivity to PCs and other equipment for the fast and convenient downloading of test data and the uploading of the electrosurgical device’s power curves and the manufacturer’s test specific programmes. 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.
