For example, the door open alarm delay can be adjusted between 1 and 5 minutes. Furthermore, the laboratory appliances with a Comfort electronic controller have a visual power failure alarm and a sensor defect alarm.
- The Comfort electronic controller is equipped with an integrated data memory which logs the maximum and minimum internal temperatures as well as the last three temperature alarms and power failures, together with the time, date and duration. These data can be read out on the display.
- Maximum temperature stability is ensured by the cooling systems of the laboratory refrigerators and freezers in conjunction with the precision Comfort electronic controller. The refrigerators are equipped with a safety thermostat to prevent temperatures below +2 °C in case of a fault. All laboratory appliances with a Comfort electronic controller are designed according to the ISO 60068-3 standard with regard to maximum temperature stability and consistency.

New data for “Suitable for monitoring” has been added to the filters on the -20°C freezers page. If your work requires independent temperature monitoring of either chamber or core temperatures, consider selecting "Yes" for this attribute. Most inexpensive spark free units do not offer fan circulation and this can cause significant temperature gradients within the chamber. Units we consider suitable for temperature monitoring have temperature variances of less than 0.1°C.
