McKesson Dual Probe Digital Refrigerator / Freezer Thermometer (°F °C) — Multiple Mounting Options & Alarm

Compact, certified McKesson thermometer designed for continuous monitoring of refrigerators and freezers. The triple display can simultaneously present high, low and current readings — either temperature (°F °C) or humidity — giving at-a-glance status. Each unit is serialized, traceable and certified; it has been tested against a standard and calibrated at the National Institute of Standards and Technology (NIST). This temperature-certified device includes two probes so you can monitor two compartments at once. The dual-probe assembly is enclosed in an unbreakable plastic vial filled with a Bio-Safe Glycol / Water medium, allowing the unit to show internal or external sensor readings. Alarm functionality features real time and date stamping, user-set low/high limits, a flashing LED visual alert and an audible beeping indicator. Multiple mounting choices make placement flexible: a flip-out desk stand, wall-mounting key hole, magnetic attachment and hook-and-loop fastener are all included for easy installation.
