TRACEABLE Cole-Parmer Traceable Precision Sentry™ Digital Thermometer with Calibration, Bullet Probe

These digital thermometers constantly monitor and display current, minimum, and maximum temperatures. Resetting the minimum and maximum temperature recorded is a simple one-button operation. Choose between three external probe types; bullet, bottle, or vaccine-bottle to suit your application needs. Probes feature a 9-ft (2.7-m) cable for placement in hoods, refrigerators/freezers, incubators, or submerged in a bath. Unplugging the external sensor will automatically activate the internal/ambient sensor. Ambient sensor has a range of -4 to 122°F (-20 to 50°C) with the same accuracy.
