Ovens Memmert Basic

Memmert Model UFB 500.

30 °C to 220 °C.
w x h x d: 710 x 760 x 550 mm
For standard temperature control applications with insensitive load, the Basic class is recommended. An electronic PID controller with an integrated self-diagnosis system ensures reliable and exact temperature control.
•    Temperature range: 30 °C (at least 5°C or 10°C above ambient) to 220 °C
•    Temperature variation (time): < ±0.5 °C at 150 °C
•    Double overtemperature protection: If the electronic heating control should fail, heating is switched off at a fixed level of 10 °C above the setpoint. In addition a mechanical temperature limiter, TB, switches off heating permanently if the maximum permitted oven temperature is exceeded by approx. 10 °C.
•    A high-quality platinum temperature sensor Pt100 (DIN class A) in a 4-wire circuit (for stable long-term transmission of measurement signals)
•    Programmable digital timer (1 min. to 99 hrs 59 min.)
Manually adjustable air flap for fresh air intake
•    Visual alarm if temperature is exceeded
•    Function signals for stand-by, operating mode, heating and overtemperature

Standard equipment
Ventilation and Control
•    forced air circulation by quiet air turbine
•    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
