ENVIRONMENTAL TEST CHAMBERS

YOU SET THE LIMITS. WE HOLD THE CONDITIONS. TESTA-CT and TESTA-TT environmental test chambers expand the Memmert portfolio with solutions for precise environmental simulation. Featuring a wide temperature range from –52 / –75 °C up to +180 °C, controlled humidity from 10 to 98% RH (CT models), and temperature change rates of up to 10 K/min on request, they ensure reliable and reproducible testing conditions.

Benefit from the combined strengths of two industry leaders. Memmert, a pioneer in climate and temperature control since 1933, and Aralab, known for its innovation in climate chambers since 1985, bring decades of specialized knowledge to the table. This collaboration ensures that customers receive the highest quality solutions, backed by the expertise of two of the most trusted names in the industry.
