Traceable® Min/Max Jumbo Refrigerator/Freezer Digital Thermometer, -58 to 158°F / -50 to 70°C with a NIST Traceable® Calibration Certificate (each)

Perfect jumbo digit thermometer for monitoring freezers, water baths, heating blocks, incubators, and refrigerators. Accurately monitor temperatures with this enclosed temperature-buffered sensor. Bottle insulates sensor from rapid temperature changes when refrigerator door is opened. Triple display simultaneously shows maximum, minimum, and current probe temperatures plus room temperature. MIN/MAX monitors high/low readings overnight, on weekends, or for any time period—a significant advantage over current reading-only glass thermometers. Range is –58 to 158°F and –50 to 70°C with a resolution of 0.1° and accuracy of ±1°C.

Signals out-of-range conditions
Alarm feature provides alert when temperature rises above or falls below set points. Alarm is programmable in 1° increments. Ten-foot micro-cable permits refrigerator doors to close on it. Solid-state probe eliminates mercury contamination in refrigerators. Probe is sealed in a miniature bottle (1 × 2-1/2 inches) filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about incidental contact with food or drinking water. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Unit is supplied with a Traceable® Certificate, flip-open stand for lab bench, slot for wall mounting, and Velcro® and magnetic strips to attach to any surface. Easy-view, jumbo 1-1/2-inch-high digits may be read from 30-feet. Sensor and 10-foot cable perform accurately even when both are under water. Supplied with one AAA alkaline battery. High-impact, chemical-resistant ABS plastic case is 3-7/8 × 4-3/8 × 7/8 inches. Weight is 4 ounces.
