The FF28LWHPLUS2 is a 2.4 cu.ft. all-refrigerator with a compact footprint for countertop use. It comes in a white finish with a locking door that includes a thermometer calibrated to NIST standards in our ISO/IEC 17025:2017 laboratory. It displays the current, minimum, and maximum temperature to the nearest tenth degree viewable in Celsius or Fahrenheit. The buffered temperature probe is stored in a glycol-filled bottle to ensure the temperature reading best reflects the temperature of other stored refrigerator contents. Inside, the FF28LWHPLUS2 utilizes an automatic defrost system for low maintenance use. Fan-forced cooling helps to stabilize the interior, with a fixed full-width wire shelf for convenient storage and a removable half shelf that can be positioned above the compressor step. This unit has a flat door liner as recommended by the CDC. A digital thermostat is located inside for convenient and precise temperature management. The FF28LWHPLUS2 can be customized with additional features, including USB data loggers and access ports. For more information, contact our sales team.
