Testing Device For Neutral Electrodes

Testing Device For Neutral Electrodes,Neutral Electrode Temperature Performance Tester

ZLR-320 Neutral Electrode Temperature Rise Tester

This device is designed according to the standard IEC60601-2-2:2017 and the Chinese national standard GB9706.202-2021 regarding the temperature rise characteristics requirements and testing methods for neutral electrodes (NE) in high-frequency surgical equipment. It can fully meet the testing requirements of standard 201.15.101.5 "Thermal performance of neutral electrodes".

According to the relevant requirements and corresponding test results for replacing volunteer testing in the standard, this testing device is designed to replace volunteer testing experiments, and the relevant test results can be considered consistent with real person testing.
