• Reads to 0.01° while monitoring temperatures in refrigerator and freezer simultaneously or two refrigerator locations, °F/°C switchable
• Triple display shows minimum, maximum and current temperatures
• Two channel alarms provide unique visual (LED’s) and audio alerts when temperature rises above or falls below user-defined high and low set points
• Unit displays the exact time and date when dual thermometer alarms are triggered, alarms are programmable in 0.1 increments
• Monitors minimum and maximum readings and displays the exact time and date when minimum and maximum temperatures occurred for both probes

Visual and audible alarms signal continuously (for days) even if temperature returns to non-alarm range. Ten-foot micro-cable permits refrigerator doors to close on it. Range is –58 to 158°F and –50 to 70°C with a resolution of 0.01° and accuracy of ±0.3°C.

Bottle Probe

Temperature-buffered bottle sensor insulates and eliminates rapid changes when refrigerator door is opened. May also be used in water baths, heating blocks, and incubators. Solid-state probe eliminates mercury contamination in refrigerators. Probe is sealed in a miniature bottle (1 x 2-1/2 inches) filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration).
