Guarantee of ±1°C/±5% RH accuracy

The temperature and humidity difference in the test chamber is the temperature and humidity maximum and minimum range, and an accuracy of ±2°C/±5% RH is guaranteed for all models. In addition, it clears the severe storage conditions* of ±1°C/±5% RH.

* Storage conditions based on Notification No. 43 of Pharmaceutical Affairs Bureau, 1991 are 40°C ±1°C/75% RH ±5% RH

Area temperature and humidity control
This equipment utilizes area temperature and humidity control. By controlling the temperature difference settings effected by test area size and ambient temperature, an accurate temperature and humidity distribution within the test area is achieved.
Uses two refrigeration circuits for a stable and reliable operation
This equipment uses two standalone refrigeration circuits to maintain operation even if one circuit should happen to malfunction. In addition, alternating refrigeration circuits can prolong their operation. This provides a secure system prepared for risk.
