Antonki 2-Pack Room Thermometer, Digital Small Hygrometer Indoor Thermometer Humidity Gauge, Temperature Humidity Meter with Max/Min Record Monitor Sensor for Home, Plants - Battery Included

Accurate out the box. Readings matched each other. I did the salt water humidity calibration, both were at 75%. Readings refreshes fast. For the price, I have no complaints.

I’m excited to try these in my outside mini greenhouse in the spring. Currently using inside and like them so far

I purchased this two-pack and one worked fine but the other had some issues with the display. I tried replacing the battery and recalibrating but it still didn't work. The other monitor works very well and the humidity and temperature readings seem to be accurate, compared to other monitors I have. Because I needed 2, I contacted the seller about the faulty monitor. They replied quickly and offered an acceptable solution. I would recommend this product - even though I had an issue, the seller clearly stands behind their product.

These work really well and don't take up a lot of space. They are accurate when compared to readings with multiple similar devices.

This review is for a set of two room thermometers. They are currently priced at $10 which seems like a very fair value considering you get two in the pack which I did not realize before I ordered them. I only needed these to test the room temperature because we are having some issues with our thermostat, so I cannot speak to the humidity sensor. For checking the temperature, however, they work great. They were very easy to set up you just pop the batteries in.

These small thermometers are very accurate and allow me to get temperature readings close to my seed starts. It also provides information on humidity, which is helpful for the same seedlings. Having two means I can monitor temps for even more plants.They use a common battery size, so it will be easy to replace when the time comes.

These are a bit hard to review since I don't have much to compare them against for accuracy. The thermostats on the wall include temperature and humidity readouts but I wanted one for the basement and the other for either the garage--so I know when it's freezing in there, or my office--just for fun. To test them, I placed them near the thermostats, and you know what, they were all off from each other a bit. The temperature was usually different by up to two degrees and the humidity by several percentage points as well. Which one is the most accurate? Hard to tell. Maybe they are meant to just be close enough? Either way, is it 40% humidity or closer to 50%? That's probably all I really need to know and these are close enough that I'll keep using them. I think the price is good and they give me the information I really want to know anyway, though I read the information with a bit of skepticism.

I got these because my office at work seemed to keep consistent temperature and I wanted to have some evidence to provide maintenance before calling them. I also have one in my basement, since our thermostat is on the first floor.
