IEC 60335-2-11 Clause 11.3 Figure 101 Surface Temperature Probe With Thermometer for Appliances

The IEC 60335-2-11 Figure 101 Surface Temperature Probe is designed for measuring surface temperature rise on easily accessible parts of household appliances during electrical safety testing. It features a tinned copper measuring disc, a K-type thermocouple, and a controlled contact force of 4±0.5 N to meet the specified measurement requirements.

Supplied with a UT320A digital thermometer, this temperature measurement device is suitable for testing drum-type dryers, upright electric cookers, cooking benches, and ovens in accordance with applicable IEC 60335 household appliance safety standards.

This household appliance temperature testing probe is used in temperature rise tests to evaluate the surface temperatures of accessible appliance parts.

Typical applications include:

• Drum-Type Dryers: Measuring temperature rise on accessible front surfaces.

• Electric Cookers: Checking the surface temperature of accessible parts during operation.

• Cooking Benches: Evaluating external surface temperatures under specified test conditions.

• Ovens: Measuring accessible surface temperatures during electrical appliance safety tests.

It is suitable for household appliance manufacturers, electrical safety testing laboratories, and product certification facilities.

The probe comes with a UT320A digital thermometer for displaying temperature readings from the K-type thermocouple. The thermometer has a measuring range of -50°C to 1000°C.

Note: The maximum operating temperature of the complete probe assembly is 80°C due to the heat resistance limitation of the polycarbonate supporting tube.
