Climate chamber MKF 400

humiditytemperaturestability

Product description
The MKF CO₂ series dynamic climate chambers are built for combined temperature and humidity testing under rapid, repeatable conditions. High change rates, precise humidity control and natural CO₂ refrigeration (R744) enable standards‑compliant test sequences and long‑term operational stability.

Benefits

• High performance with cost‑efficient lifecycle characteristics
• Easy integration, intuitive touchscreen control and flexible networking
• Secure handling of samples, measurement data and test processes
• Reproducible results and stable operation for serial testing

Important characteristics

• Temperature range: -50°C to +180°C
• Humidity range: 10% to 98% RH
• Humidity control with capacitive sensor and steam humidification
• APT.line™ preheating chamber technology
• Cooling with natural CO₂ (R744) refrigerant
• Intuitive touchscreen controller with time‑segment and real‑time programming
• Ergonomically adjustable operating terminal and signal triangle status display
• Stainless‑steel inner chamber, heated viewing window with LED lighting
• Internal data logger; data export via USB and interfaces Ethernet/USB (optional RS485)
• Integrated 20 L water‑storage tank; door heating and programmable condensation protection
• 1 stainless‑steel rack (std.), load per rack 30 kg; permitted load 150 kg
