Environmental test chambers from the APT.line™

MKT 240 (E3)

Environmental simulation chamber for complex temperature profiles in the low temperature range

The MKT test chambers meet all requirements for testing under extreme temperature conditions between -70 °C (-94 °F) and 180 °C (356 °F). The outstanding heating and cooling speeds permit even faster temperature changes and more complex test cycles to be performed.

1) Lower values are valid at an ambient temperature of max. 25 °C (77 °F)
2) Depending on the set-point
3) to 98 % of the set value
4) These values can be used for dimensioning air condition systems.

All technical data are specified for units with standard equipment at an ambient temperature of  25 °C (77 °F) and a voltage fluctuation of ±10 %. The temperature data are determinated in accordance to factory standard following DIN 12880 respecting the recommended wall clearances of 10 % of the height, width and depth of the inner chamber. All indications are average values, typical for units produced in series. We reserve the right to alter technical specifications at all times.
