VOKARO Small Thermometer Outdoor with Temperature Probe for Outside Thermometer, Greenhouse Thermometer, Weather Thermometer, Water Thermometer(4 Pack)(Black)

We used these thermometers for a Science Fair project and they each had to be reading the same temperature. We were expecting that they would not be in sync but they were. Perfect size and price for our project. Came with extra batteries and in a nice storage case

This digital thermometer with wired sensor works perfect for my aquariums. The wired sensor is about 3' long. They have side clips in case you would like to cut a rectangle-shaped hole in some material and pop these in to look like an instrument cluster. Great price.

Bought these to install one on my motorcycle, others will be used to check garage and basement temps or spares. Most aftermarket motorcycle thermometers do not have a separate sensor so are wildly inaccurate when the sun hits them. I plan to put the sensor under the fairing so it sits in a shared area. I was not surprised to find that all four do not show the same temperature but they are close enough for my purposes and seem to be within the 2% accuracy listed. One of the four is consistently 1.5° lower than the two that are the same. Two are always the same, the fourth is always 0.2° higher than those two. In comparison to a desktop digital thermometer, the two that are the same are about 0.3° high but I don't know if the desktop thermometer is accurate. The displays are plenty large and easy to read. The access door for the batteries is on the back of the units so surface mounting would be difficult. I plan to cut out a slot in a plastic panel to mount the thermometer; it has clips on both sides to hold it in place. Not sure how long the batteries will last as I just received these yesterday. Overall for the price and reasonable accuracy I'm happy.

I've owned this set of thermometers for 4 months now. I've already had to replace the batteries in two of them so far. Over time as the batteries go dead the temperature being displayed on the screen starts to read higher and higher. I changed the batteries in one of them today and the displayed temperature instantly went down 2.7 degrees once the new batteries were installed. The attached picture shows some thermometers with new batteries and some with old.

I wasn't expecting a whole lot from these inexpensive thermometers with probes, but I'm pretty impressed. The 4 units register within 4 tenths of a degree of each other. More often then not, at least 2 or 3 register the same. I placed one outside in a sheltered area and it registered a chilly 43.2 degrees this morning (very close to what the Weather Channel says for my general area). And the inside usage shows temps very close to what my heating unit thermostat registers. Not only are the extra batteries a nice touch (the batteries in the units were already functioning), but the box they came in is really cute and can be used for any number of other storage ideas. Great little find!!!

Using the thermos to monitor 2 walkin coolers (thermo outside units, sensor inside) The remote reading is very useful. It's sometimes difficult to read. But it responds very quickly and all 4 were reading the same temp. Bery nice that they included an extra set of batteries.

I put these in the air conditioner output flow stream to make sure my air conditioners are working correctly. All temperature sensors worked great and read the same when I tested them. I was also surprised they came with spare batteries...good deal!!

I don't understand reviews saying 'they read off' still having more than one star. They read several degrees too high. The most important part of a thermometer is that it reads the temperature in a reasonable window. I don't care if it's cheap quality otherwise, but a thermometer should accurately read within less than one degree fahrenheit.
