2500L temp.and humidity chamber (a distributor who sold American Thermotron equipment and bought one test chamber from us for try) said: The stability of STS chamber is too good.
He said: STS test chamber is very stable. The test chamber we bought originally use to run -20 degrees testing condition. Our test chamber could run to -40 degrees testing condition, and it is no problem to put 5 vacuum cleaners in and run with load. But the American Thermotron equipment can not do it.
In the past ,it made me spend so much money to buy Thermotron equipment in the United States. Haha, I’m so happy to receive the customer’s approval, and we will continue to work hard.
