These Lab Companion TH3 temperature and humidity environmental chambers provide excellent control, making it easy to achieve uniform humidity and temperature distribution by circulating air in the chamber at the optimum speed. Efficient water supply and recirculation system minimizes water refilling even for long-term high-humidity tests. Chambers feature control and data process by connecting unit to a PC via RS-485 port.

Chambers provide enhanced safety with multiple protections and alarms. Chambers feature electronic over temperature shutdown, low and empty water level alarm and shut off, door open warning and shut off, overcurrent and short protection, compressor overload and overheating shut off, and high/low refrigerant shut off.
