Professional Testing Device For Neutral Electrodes. IEC 60601-2-2 — medical electrical equipment — particular requirements for high frequency surgical equipment. Neutral electrode temperature-rise testing checks that the return electrode does not heat tissue beyond the permitted rise under continuous load. This unit is built by Kingpo for bench use in a medical electrical safety laboratory, and it is supplied with a calibration certificate.

What it measures

The quantities named in the applicable clause of IEC 60601-2-2
Worst-case supply and load conditions, selected from the front panel or automatically
Pass/fail against the limits entered by the operator, with the reading retained for the report

Specification

How a test run works

Configure the supply condition and the measuring device arrangement the clause requires.
Connect the equipment under test, including any applied part and earth reference.
Select or program the sequence: normal condition first, then the single-fault conditions.
Run, capture the readings and compare them with the allowable values in the standard.
Store or print the result set; the test report needs every condition, not just the pass.

Buying notes

Confirm three things before ordering: which edition of IEC 60601-2-2 your market requires, whether you need the single-fault conditions automated, and what load range your products actually present. Sending us the clause numbers you test against is usually faster than comparing model names.

Frequently asked questions

Is the unit calibrated before despatch?

Yes, and we re-calibrate on request.

Can it be supplied for 110 V?

Yes — other supply voltages and plug types are available; tell us the market.

Do you provide the test procedure?

We supply the operating procedure and, where the standard allows, the test sequence pre-programmed.
