Traceable 4239 Hi-Accuracy Refrigerator Thermometer with Bottle Probe

Traceable® Hi-Accuracy Refrigerator Thermometer

High accuracy thermometer can monitor two different areas of any refrigerator or freezer

• 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

Records time and date for min/max readings and hi/lo alarm alerts

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).
