P.S 1 “DHS”is the pattern symbol of low temperature constant temperature and humidity test chamber.
2, All the data are taken in condition of 25℃(QT) and the working studio has no load
3, We can make nonstandard low temperature constant temperature and humidity test chamber according to the demand of the customer. |
