BINDER MKF 240 climate chamber
The versatile environmental simulation chamber is ideal for professionals who want to carry out precise cooling and heating tests in accordance with common DIN and IEC standards. With its generous interior capacity of 228 litres and the extended temperature range of -40 °C to +180 °C, it covers a wide range of tests. In particular, the integrated humidity control, enhanced by a capacitive sensor and fast-response vapour humidification, makes it the first choice for users who rely on precise climate fluctuations. Compared to similar appliances, this model offers several unique selling points such as automatic water and waste water supply and APT.line preheating chamber technology, which ensures a more homogeneous temperature distribution.
Optimised temperature and humidity control
Vapour humidification is used for precise climate management, which ensures uniform humidity within a very short time. The humidity can be set between 10 % RH and 98 % RH, allowing even complex humidity load scenarios to be realised. Thanks to the touchscreen controller with intuitive navigation, extensive programming options are available for time interval and real-time programmes. Measured values can be read out externally and conveniently documented via the Ethernet interface, while the internal memory and diagnostics system supports smooth continuous operation. Another plus is the heated viewing window with LED interior lighting, which ensures a clear view of the test samples at all times and minimises the risk of condensation.
The integrated water reservoir with a volume of 20 litres eliminates the need for frequent refilling and ensures a continuous test procedure thanks to the alarm function in the event of a water shortage. Furthermore, four potential-free switching contacts ensure high flexibility when integrating into external monitoring systems. A highly efficient compression refrigeration unit and the environmentally friendly, CFC-free refrigerant R-452A ensure sustainable and powerful cooling. To improve the protection of sensitive samples, programmable condensation protection can be activated. It minimises potential moisture damage and increases the reliability of the climate tests.
