Buffered probe

Displays minimum/maximum temperatures for the previous 24 hours (for each hour) and previous 7-days (for each day); or previous 30 days (for each day). The time/Date stamp key shows the exact time and date for all minimum and maximum readings. A 4-wire platinum sensor ensures linear response and high accuracy across the entire range. Range: –58.00 to 158.00°F (–50.00 to 70.00°C). Resolution: 0.01°. Accuracy: ±0.1°C; fulfills precise requirements for refrigerators/freezers. The sealed bottle probe version is insulated from rapid temperature changes when door is opened. Sealed bottle liquid is GRAS— liquid generally recognized as safe by US Food and Drug Administration. The refrigerator/freezer door closes and seals tightly around the micro-thin cable. The triple display shows current and minimum/maximum temperatures. The alarm is settable in 0.1° increments and signals when the temperature rises above/falls below set points. Visual LEDs and audible alarm signal continuously, even if the temperature returns to the non-alarm range.
