The universal oven for precise, absolutely reliable and safe temperature control in science, research and material tests in industry.

Ventilation And Control
  • Natural convection
  • Continuous adjustment of pre-heated fresh air admixture
  • Vent connection with restrictor flap
  • Microprocessor PID-temperature controller with integrated autodiagnostic system with fault indicator
  • One Pt100 sensor class A in 4-wire-circuit
  • Integrated digital timer (1 min. up to 99 h 59 min) to switch off heating to stand-by mode
  • Digital LED- display of set and actual temperature as well as remaining process time
  • Resolution of display for set value and actual value 0,5 °C

Over Temperature Protection (double) 
  • In case of total breakdown of sensor, the heating is switched off at approx. 10 °C above set value
  • In case of failure of the switching element, the heating will be controlled by an additional relay approx. 10 °C above the set temperature
  • In case of a faulty sensor (incorrect measuring values) or the total breakdown of the controller the heating is switched off at approx. 10 °C above the max. oven temperature by the mechanical temperature limiter TB protection class 1
  • For very sensitive and/or valuable load in terms of being non-reproducable, we recommend ovens of our E- and P-class guaranteeing an even higher safety standard
