LT/LH Series


Compact, quiet, yet powerful units are required to tackle special laboratory conditions that include limited space, even smaller specimens and the need to conduct tests directly at the workplace. Temperature and climatic testing aims to prove the resistance capability of test specimens to the environmental influences of temperature and temperature, combined with humidity (climatic testing).

As tests concentrate on the durability of materials and substances under extreme conditions, as well as malfunctions of component. The LT & LH series of temperature and climatic test chambers are ideally suited to such applications. Reductions in the effectiveness of substances can be detected at an early stage and thus already eliminated in the development phase.

These systems have a volume of 34 L, 64 L and 100 L respectively and provide an optimum solution where space is limited. Please refer to the Technical Data table for the most important technical details.
