Hollow glass dew point meter (dry ice refrigeration)

2024-05-31 14:33

  Product Introduction

  To measure the dew point of insulating glass, the measuring device is generally placed on the surface of the sample, cooled to a temperature equal to or lower than -60 ℃ and maintained at this temperature. After reaching the set time, the condensation of the sample is observed. The dry ice type hollow glass dew point meter utilizes the low temperature point of dry ice to meet the requirements of our test.
