Environmental test chambers from the APT.line™

MKF 240 (E3)

Environmental simulation chamber 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. Tap water [municipal] with a max. hardness of 8.0° dH = 1.4285 mmol/l.
    (The hardness can be established from the water analysis of your water supplier.)

2. We recommend the BINDER Pure Aqua Service for longer maintenance intervals, regardless of water quality.

3. Demineralized or deionized water available at the customers location.

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) Upon door opening > 1.5 % RH, recovery time approx. 20 min.
5) Within a range from 25 °C (77 °F) to 95 °C (203 °F) and < 90% RH

All technical data is specified for units with standard equipment at an ambient temperature of 25 °C and a voltage fluctuation of ±10 %. The temperature data is 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.
