Digi-Sense, 98767-51, Traceable High-Accuracy Fridge/Freezer Thermometer with Calibration; 1 Vaccine Bottle Probe98767-51 Includes Only:ThermometerVaccine bottle probe with 10-ft (3-m) cableMagnetic stripsHook-and-loop stripsBench standBatteriesNIST-traceable calibration certificate with data.Features:NIST-Traceable certificate from A2LA accredited (1750.01) calibration laboratoryResolution of 0.01° and accuracy of ±0.6°F (±0.3°C)Visual and audible alarms signal continuously until resetBottle probe insulate sensor from rapid temperature changes Vaccine bottle is designed to fit vaccine traysTriple-display - view MIN, MAX, and current temperature simultaneously.Easily and accurately monitor temperature in most scientific, industrial, or general-purpose applications. Built-in alarms alert continuously until reset. Unit displays the exact time and date when thermometer alarms are triggered. Program the alarm in 0.1° increments. Meters that accept two probes are ideal for monitoring two unique areas that are near each other. Probe comes with a microcable that permits a door to close on it.Traceable Products have an individually-numbered Traceable Certificate provided with each unit, that assures accuracy from ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.Thermometer comes with a vaccine bottle probe filled with nontoxic glycol, eliminating the possibility of contamination from mercury. Solution is GRAS (generally recognized as safe) by the FDA.
