🌡️ 2-Pack Mini Digital Hygrometer Gauge Indoor Thermometer by Meggsi - LCD Monitor for Temperature and Humidity Measurement in Humidors, Greenhouse, Jars, Incubators, Guitar Case - Fahrenheit Display (℉) Review

I use this product to control the internal temperature/humidity of peppers. I start spring planting in the middle of winter. They are small and fit in the corner of 2 cells so they fit perfectly in the dome. I use another one outside the dome to control the air temperature. Compared to other thermometers, it is accurate and does the job. This works fine for my needs.

I chose this product because it was very cheap and it came in a 2 pack. I was a bit hesitant as it only had 4 reviews in a short amount of time. . However, I was pleasantly surprised at how accurately both react to changes in temperature and humidity. I highly recommend this product. I've added a picture of their size compared to my car key, they don't have built in magnets or anything but they are perfect to leave in different rooms on a table or something.

I have this to monitor incubator humidity for which it works well. However, the temperature readings in the incubator are very wrong. At first I thought I had a problem with the incubator as both meters showed the same thing, but another shrew confirmed that the incubator readings were fine. When it's in room air the temperature and humidity are correct, but in an incubator the humidity appears to be correct but the temperature read is 96.2F when in fact it's 99.5F. So if you're buying this for

Neither device was within the specified +/- 5%. Tested on a freshly calibrated high quality (expensive) areometer. I agree as I wasn't expecting much. I can just compare them with a calibrated device and do some quick calculations. However, I would expect them to appear at least within 5% +/- of each other. Not even close compared to each other. Block #1 differed from block #2 by almost 12 degrees, and the humidity of #1 was 40% and #2 - 10%. I unplugged the batteries for 12 hours to restart…
