Thomas - 4239 Traceable Hi-Accuracy Refrigerator Thermometer, with 2 Bottle Probe,58 to 158 degree F

Get precise and reliable temperature measurements for your refrigerator with the Thomas 4239 Traceable Hi-Accuracy Refrigerator Thermometer. This thermometer is NIST traceable and meets all CDC requirements for thermometers and vaccine thermometers, so you can trust its accuracy. With a temperature range of -58 to +158 degrees Fahrenheit (-50 to +70 degrees Celsius), this dual-read thermometer is suitable for use in refrigerators, water baths, heat blocks, and incubators. It has an impressive accuracy of +/- 0.3 degrees Celsius, ensuring you get the most accurate readings for your temperature-sensitive items. The Thomas 4239 comes with the choice of a temperature-buffered bottle sensor or a probe-style sensor.

The probe sensors are waterproof and chemically-resistant, with a 3/16 inch diameter and a length of 3/4 inch. The temperature-buffered bottle sensors contain non-toxic glycol, which helps insulate the probe and minimize temperature fluctuations when the refrigerator door is opened. This solution is recognized as safe by the FDA. The thermometer features a three-line LCD that simultaneously displays the minimum, maximum, and current temperature for one probe at a time.

You can set temperature alarms in 0.1 degree increments, and the two-channel alarm provides both visual and audible alerts for out-of-range temperatures for each probe independently. Even if the temperature returns to normal, the alarm will continue to sound until manually silenced. For convenience, the thermometer has receptacles for up to two probes, allowing you to monitor multiple areas of your refrigerator. It also records the date, time, and length of time the probe was exposed to out-of-range temperatures, providing valuable data for analysis and monitoring. The Thomas 4239 is designed with a high-impact, chemically-resistant ABS plastic case that can withstand the rigors of a busy kitchen environment.

It comes with a built-in stand and wall mounts, or you can easily mount it with Velcro or magnetic strips. The thermometer is powered by two AA batteries (included), providing up to one year of continuous monitoring.
