iapsales Easy to Read: Refrigerator Freezer Thermometer Alarm, High & Low Temperature Alarms Settings, Stainless Steel & White

The thermometer seems well built and the digital display is bright with good contrast and easy to read. It came in the mail in two days without any damage and after I installed an AAA battery (not supplied) it worked as advertised. When checked against a laboratory grade glass thermometer traceable to NIST standards, the thermometer was only one degree off at 0 degrees F. well within its specifications. The temperature sensor tip is 4mm (5/32") in diameter, x 25mm (1") long. The probe wire is round, 2mm (5/64") in diameter x 153mm (60 1/4") long and seems sturdy enough not to break in normal use. However the wires does get stiff at freezing temperatures. The display unit has a flip-out stand that is easy to open and a magnet powerful enough so that the display does not fall from a vertical (steel) surface or the top of a chest type freezer when the lid is opened and closed. Unlike many other devices I have owned, the lid to the battery compartment to this display is easy to open and close. The high and low alarm limits were simple to set and worked as advertised when I tested them. I do value that the alarm keeps sounding until the alarm button is pressed to re-set it. I have a chest type freezer and when I first got the thermometer I just ran the probe wire over the top edge and closed the lid. Some ice formed around where the wire entered the freezer, not a lot, but some. I followed another users suggestion and ran the wire under the gasket. In my case I could not pull the gasket from the lid without tearing the gasket so I pulled the gasket out from the lid, stretching it enough to expose the thin connecting web and using an ice pick, punched a hole and ran the wire through the hole. Problem solved.. no ice. I am a regular Prime customer and paid the listed price for this unit and do recommend it.

Works great

Freezer alarm part seems to work great once set up. However: 1) I bought 2 of these. One beeps considerable louder than the other one. Not good. 2) Buzzers are located on the back and sound leaks out through some slots. When you mount it using the magnets, which most people would probably do, the buzzers are extremely muffled. Not good. In a high noise environment, there's no way you're going to hear it. 3) Hi-lo temp readings can only be reset by removing the battery. Not good. Not sure if this would knock out your freeze warning settings or not. 4) Hi-lo temperature readings can only be displayed by pressing a depressed button on the back. Inconvenient. Also, if you accidentally leave it on Min or Max you may begin to wonder why the thing seems frozen and unresponsive. 5) Setup is difficult and would be impossible without instructions as there's nothing you could intuitively figure out. None of the shortcomings are a deal-breaker for me. Not disappointed with main function of protecting my frozen supplies. It's reassuring when you open the door too long and the thing starts beeping showing that it's doing it's job. FYI, the sample rate is 10 seconds between readings, I suppose to extend battery life as it only takes a single AAA battery. Looking at reviews for some of the other freezer alarms, this seems to be the one to get. Hits right on that price/reliability ratio. Unless something weird starts happening, these are the ones I'm sticking with.

Easy to set up, easy to read. I bought one to try it out this is my second one for my other freezer.

Works good. Bought 3 and checked calibration against other 2 other gauges. All 5 read within a degree of each other at 70F and 30F, so I trust this set is accurate enough for my needs.

No directions for setting alarms and unless seller can provide directions, I'll be returning product. You would think setting alarms would be easy but pressing the 3 buttons in various ways did not help and it's not like I haven't set up many other products. Screen response to pressing buttons was also not consistent.

Works good

I bought 8 of these for my small restaurant refrigeration monitoring. They are easy to use and read. But. two out of the eight had faulty probe wires. One malfunctioned immediately and one after about a week. I was frantic thinking my refrigerator was not keeping cold, emptied it out, called customer service, etc. Then I decided to try a different thermometer and figured out the original probe wire was misreading. My refrigerator was 38 degrees but the probe wouldn't read lower than 45. Although I like this product, I won't purchase it again because 2 out of 8 malfunctioned within the first week of use.
