Traceable dual thermometer displays the temperatures of two separate probes in degree C and degree F. Allows putting one probe in the freezer and another in the refrigerator (or measure two areas of a refrigerator). Range is -58 to 158 degree F with a resolution of 0.1 degree and an accuracy of +/-1 degree C. Displays date and time when minimum and maximum temperatures occur. Audible and visual alarm feature provides alert when temperature rises above or falls below two set points. Alarm is programmable in 1 degree increments. 3.5' micro-cable permits refrigerator doors to close on it. To assure accuracy an individually serial-numbered Traceable certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). High-impact, chemical-resistant ABS plastic case. Measures 3.5" length by 1.75" width by 1" thick. Weight is 3-2/3 ounces. Supplied with flip open stand. Velcro and magnetic strips are provided for mounting of both thermometer and bottle sensor.

I ordered these thermometers because I need thermometers with IN DATE calibration for storage of the COVID-19 vaccine. These thermometers arrived in Dec 2020 with calibration certificates that EXPIRED in April 2020!

It's worked well for several years now. Only reason I went down a star was because the alarm is so soft, it's not noticeable.

Great price for the job. We had 4 people try to figure out the alarm and no one can figure it out. Otherwise I use one for a refrigerator and one for a freezer. I really don't need two temperatures but the price was good and It was calibrated and has an expiration date. I need that for research

This is an AWESOME product. I use it to simultaneously record the temperature inside of my tent and outside at the same time, and capture the high and low temps while I sleep. This is helpful as I test different camping products and want to know how they're performing.The instructions are easy to follow. This is a high-quality product. The magnetic back is strong enough to hold it on a vertical surface. The probes (on this model) have suction cups to hold them secure, but I haven't needed them. The probes on this model may also be submerged, if you need that feature.

I use this in my refrigerator, and if I put the two probes in the same area, their readings are virtually identical! I was definitely not expecting this. I will be calibrating my other thermometers to this one.

Despite the fact that that two sensors are very nearly side by side in my home chest freezer, they register temperatures that are usually about 4-5* apart. This level of accuracy is adequate for my needs, but it may not be sufficiently accurate for those with more demanding requirements.
