The McKesson Refrigerator/Freezer Thermometer with Triple Display is a professional-grade tool designed for precise temperature monitoring in medical laboratories, vaccine storage, and food safety environments. It features a single probe for fridge or freezer use alongside ambient room sensing, displaying current, minimum, and maximum temperatures simultaneously on a large, easy-to-read screen. Compliant with CDC and VFC guidelines, it includes NIST-traceable certification, making it ideal for users who need reliable data for audits and compliance.
Standout features include programmable high/low alarms with audible and visual alerts, a 10-second refresh rate, and accuracy of ±0.5°C. The probe is housed in a unbreakable vial filled with bio-safe glycol solution to accurately replicate vaccine storage conditions. In real-world use, it provides continuous updates and time/date stamps during excursions, helping prevent losses from temperature fluctuations.
Build quality is robust with a waterproof casing, multiple mounting options like a fold-away stand, magnet, and hook-and-loop, plus dimensions of 8.25 x 5 x 2.5 inches for stable placement.
