Environmental test chambers from the APT.line™
MKF series:
Environmental simulation chambers for complex alternating climatic profiles
The MKF series is ideally suited for all tests in accordance with current temperature and climatic test standards based on DIN and IEC standards. The required temperature and humidity values can be attained rapidly and maintained accurately, even under extreme conditions. The unparalleled ease of operation as well as extensive standard features provide that ‘little extra’ in handling.

1) Temperature range 25 °C to + 95 °C (+ 77 °F to + 203 °F) and < 90 % r.H.
* Valid at an ambient temperature up to 25 °C (+ 77 °F)
All specified technical data apply for standard equipment operating at an ambient temperature of + 25 °C (77 °F), with line voltage fluctuations of ± 10%. These typical average values for series equipment were determined in accordance with the BINDER factory standard. They are based upon the recommended distances from the inner chamber walls, namely 10% of height, width and depth. Differing ambient temperatures or variances in the design of individual equipment may produce different performance data.
We therefore recommend that equipment be calibrated and/or validated on a case-by-case basis when working at the extremes of the permissible ambient temperature range.
