3M Temperature Test Corner Electrical Appliance Testing Equipment
IEC60335-1 3M Large Temperature Measuring Test Corner
Equipment Overview:
This test corner meets the requirements of IEC 60335-1:2016 “Household and similar electrical appliances-Safety-Part1:General requirements” clause 11.
The test corners are mainly used to provide environmental conditions that meet the standard requirements for temperature rise testing of various electrical and electrical products.
The test corners with different distribution specifications, numbers of temperature measuring points and external dimensions can be customized according to the actual tested samples.

Test Principle:
Thermocouples used for determining the temperature rise of the surface of walls, ceiling and floor of the test corner are attached t the back of small blackened disks of copper or brass, 15mm in diameter and 1mm thick. The front of the disk is flush with the surface of the board. The thermocouples are connected to the temperature measurement instrument to monitor the temperature at each point in real time.
Customized service:
Sinuo can customize different sizes with different temperature measuring distribution according to client's specific requirements. And our test corners are well painted, the themocouples and measuring coppers are well arrayed, all the themocouples are leaded to the terminal block, which is covenient for client to connect to the temperature measuring and recording instruments.
