Memmert Universal oven Model UNB 400

Standard equipment

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
  

Overtemperature 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
