FAQ

What is the difference between the TH-G Temperature and Humidity Chamber and the TH-I Temperature and Humidity Chamber?

The only difference is the humidity profile is slightly different. Unless that minor change is valuable, we recommend the TH-G as they cost a few thousand dollars less.

 

Is the viewing window included as a standard feature? Can I get a larger viewing window?

Yes, the viewing window is a standard feature.

The size of the viewing window cannot be changed, however we can install an inner glass door which would allow you to open the outer door and have a more complete view of the inner chamber without breaking the seal of the chamber. If you would be interested in getting a Jeio Tech environmental chamber with an inner glass door, please contact us for pricing and details.
