All technical data are specified for units with standard equipment at an ambient temperature of 25 °C and a line voltage fluctuation of ±5%. The temperature data is determined 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 figures are typical average values for series devices. We reserve the right to alter technical specifications at any time.

Temperature measurement of the specimen

Temperature measurement of the specimen

Additional PT 100 temperature sensor for accurate temperature measurement of the specimen and digital display of measured values. Recording of measured data via RS 422 interface possible.

Door lock

Door lock

Prevents unauthorized access to the process sequences in the chamber.

Calibration certificate & validation

Calibration certificate & validation

BINDER can significantly reduce the workload in qualifying and validating devices. Nobody knows our devices as well and has as much experience in certifications as we do.
