Traceable® 6416TR Precision Sentry™ Digital Thermometer with Glass Bottle Probe

Traceable® 6416TR Precision Sentry™ Digital Thermometer with Glass Bottle Probe

The Traceable® Digital Thermometer with Glass Bottle Probe provides continuous monitoring of current, minimum, and maximum temperatures in refrigerators, freezers, incubators, vaccine storage units, and other temperature-critical environments. Featuring a temperature-buffered glycol bottle probe that simulates the thermal characteristics of stored products, this thermometer delivers more meaningful readings than ambient air measurements alone. Each unit is precalibrated to NIST-traceable standards for dependable monitoring accuracy.

Key Features

• Triple display simultaneously shows current, minimum, and maximum temperatures
• Simple one-button Min/Max reset operation
• Selectable external bottle probe or internal ambient sensor
• Switchable °F/°C display
• Glass bottle probe filled with nontoxic glycol solution
• Temperature-buffered bottle probe mimics stored product temperatures
• Glycol solution is GRAS (Generally Recognized As Safe) by the FDA
• 10-foot microcable allows refrigerator and freezer doors to close securely
• Includes NIST-traceable certificate from A2LA accredited (1750.01) calibration laboratory
• 1-year warranty

More About This Item

This digital thermometer continuously displays current, minimum, and maximum temperature readings, providing a complete picture of environmental conditions over time. A convenient one-button operation allows users to quickly reset recorded minimum and maximum values for daily or routine monitoring.

The temperature-buffered glass bottle probe contains a glycol solution that closely simulates the thermal response of vaccines, reagents, pharmaceuticals, and other stored products. By reducing the effect of short-term temperature fluctuations caused by door openings, the bottle probe provides a more representative indication of actual product temperature.

The external probe allows accurate monitoring inside refrigerators, freezers, incubators, and environmental chambers. When the probe is disconnected, the thermometer automatically switches to the internal ambient temperature sensor. The ambient sensor measures from -4 to 122°F (-20 to 50°C) with the same specified accuracy.

The included 10-foot microcable is designed to pass easily through refrigerator or freezer doors while maintaining an effective seal. Multiple mounting options, including wall mounting, magnetic mounting, hook-and-loop strips, desktop placement, and a dedicated probe holder, offer installation flexibility.

Each Traceable® instrument includes an individually numbered Traceable® Certificate verifying accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. Measurements are traceable to SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. This rigorous validation eliminates the need for separate calibration, saving both time and cost.
