Product information:
The test device is suitable for sealing parts and enclosure’s sand and dust resistance capacity testing of the electrical and electronic products, car and motorcycles spare parts and seals. In order to detect the use, storage, transport performance of the electrical and electronic products, car and motorcycles spare parts and seals under the sand and dust environment.
The inner of the test equipment is made of high quality SUS304 stainless steel, the enclosure is with cold-rolled steel electrostatic spray. And it is also has large observation window and manual wiper device. The security protection is good.
The test equipment uses intelligent digital temperature controller, humanized operation design, and different grades of meter operation functions are compatible. The input with digital calibration system, built-in common thermocouples and RTD nonlinear correction form, measurement is accuracy and stability. With position adjustment and AI adjustment function,
0.2 precision, multi-alarm mode.
The sand and dust test chamber is designed and manufactured according to IEC60598-1.
