Climate chamber MK 720

humiditytemperaturefor rapid temperature cycling

Product description
The MKF 720 CO₂ climate test chamber is designed for combined dynamic temperature and humidity tests with high change rates and precise humidity control. It supports reproducible, standards‑compliant test sequences and is equipped with a comprehensive set of standard features. The refrigeration circuit uses natural CO₂ (R‑744) suitable for applications with specific cooling requirements.
