Climate chamber MKF 240

humiditytemperaturefor environmental simulation

Product description
The dynamic climate chambers of the MKF CO₂ series are designed for combined temperature and humidity tests under dynamic conditions. High change rates and precise humidity control enable reproducible, standards-compliant test sequences. The standard feature set covers common laboratory and production requirements. The MKF CO₂ series uses natural CO₂ (R744) as refrigerant and provides a solution for combined climate testing with controlled condensation protection.

Benefits

• High dynamic performance for controlled thermal cycling
• Compact 228 L interior for sample-focused testing
• Simple integration and intuitive touchscreen control for laboratory use
• Data integrity via internal logger and open-format USB export

Important characteristics

• Temperature range: -50 °C to +180 °C
• Humidity range: 10 % to 98 % RH
• Humidity regulation with capacitive sensor and steam humidification
• APT.line™ preheating chamber technology
• Cooling with natural CO₂ (R744)
• Intuitive touchscreen controller with time-segment and real-time programming
• Ergonomically adjustable operating terminal and illuminated signal triangle
