Application

Drawell Constant Temperature Humidity Chambers have a precise temperature and humidity control system. It provides various environmental simulation conditions for industrial research and biotechnology testing. It’s widely used in aseptic tests and stability inspection in medicine, textiles ,food processing, industrial Product raw material performance, product packaging ,product life and other tests.

DW-LTH Series

1. Large LCD screen to display more data simutanously. Menu-type operation interface.
2. PID microprocessor ensures precise control for temperature and humidity .
3. There are 99 cycles of program, each cycle is divided into 30 segments. Each segment contains 99 hours and 99 minutes of cycle steps. It can happily meet almost all the complicated experiment process.
4. Temperature -limiting alarm system ensures experiment runs safely. If the temperature exceeds the limit, the operation will be automatically stopped and alarm will prompt the operator.
5. Double door designed, tempered glass inner door for easy observation.
6. Equipped with leakage protection.
7. Equipped with spare temperature control which ensures the product work normally even the main temp.control failed. (for heating).
8. With USB for data download.
