SE 300 Humidity
Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
How it works
The chamber can be equipped with Thermotron’s patented modular humidity system for simultaneous temperature and humidity testing. The modular humidity system can be included at original order or added later as a field retrofit.[2]
The SE-300 features the 8800 Controller. The controller includes a Power Saver mode that selects single-stage or cascade operation based on temperature setpoint to reduce energy consumption. The chamber also includes a System Monitor for self-diagnostics and a Serial Communications Panel with USB, Ethernet, RS‑232, and optional GPIB connections.[2]
