IEC 60335-2-103 Probe for Measuring Surface Temperatures
A specific instrument for determining the surface temperature of different electrical equipment is the IEC 60335 surface temperature measurement probe. IEC 60335-2-9:2019 clause 11.3 Figure 105, IEC 60335-2-11 clause 11.3 Figure 101, and IEC60335-2-6-2002 clause 11.101 Figure 104 are just a few of the strict international standards that this probe complies with.
According to IEC 60335-2-103:2023 Figure 103, such as requirements preconditioning of household and similar electrical appliances drum dryers and in vertical ranges, hobs, ovens and other were surface temperature rise measurement.
Model: TT-T20
Measurement of the surface: Diameter 5 mm * 0.5 mm tin copper
Bushing: Inside diameter 3 mm, Outside diameter 5 mm
