IncuTherm Digital Thermometer Hygrometer with Min/Max Memory

Great little hygrometer. Accurate and consistent compared to my other calibrated hygrometer, and consistently reads the same as my factory calibrated Brinsea incubator. The thermometer is 0.3 degrees off, compared to my incubator and spot-check thermometers, but its a consistent 0.3 degrees so easy to adjust for if I use it on its own in my cheaper incubator. I've been through 3 other hygrometers and 4 other thermometers in the last 3 years of hatching chicks and ducklings, and this one is the most reliable and best value for money too.

This thermometer/hygrometer is helping to keep my chickens healthy during this extreme cold blast. I plan to use it for incubating chicken and turkey eggs, but for now it's in the chicken coop where I can monitor not only temperature, but critical humidity levels as well. I've been able to adjust the coop's ventilation based on humidity to prevent frostbite in spite of extreme cold. I've had them locked inside for 6 days so far, and all are healthy and happy. When I first received it, I ran a humidity test with a spoonful of salt, water enough to wet the salt, sealed with the unit in a ziploc bag. It was spot-on at 75%.

Humidity reading was accurate. Temperature reading was off by 1 degree. Worked well for my incubator.

I bought this for monitoring max/min temperatures in a greenhouse. It worked like a charm. It is easy to use and set up. It is very accurate. I would recommend this to anyone who needs to monitor temperatures in small places.

Item came fast! Accurate readings!

This is the second time I've ordered these exact temp/humidity digital readers. I gave the others to friends who needed them for their incubators. They are very accurate and I use them all the time and rely on them soley for my incubators.

I need an accurate temperature and humidity monitor for my garden, and frankly all the other ones I tried for that purpose were terribly inaccurate. I figured accuracy was extremely important for incubating, so I gave this a try. It works wonderfully. I love the magnetic backing. My only gripe is I wish the temperature numbers were bigger than the humidity, but I figure humidity is probably more important for incubation. But I guess what I really want is for this manufacturer to make a model for gardening :)

mine worked good for awhile but now it shows humidity but the temp reading has this on the screen-LL.l of course i have no clue how to fix
