AcuRite Digital Thermometer with Indoor, Outdoor Temperature and Daily High and Lows (00424CA), White

This is our second purchase of an indoor-outdoor thermometer. It works well and is sufficiently accurate (within 1 or 2 degrees of other reliable temp gauges). Has been thru a winter in a protected area outdoors and still works. It is relied on daily.Ver easy to set-up and use.

Use this Digital Thermometer in our Greenhouse. Sensor placed in Greenhouse with Lithium batteries. Initially tried Alkaline batteries for outside sensor and received incorrect readings. Changed to Lithium batteries and the unit worked perfect. Lithium batteries have a higher tolerance for low temperatures. Greenhouse is about 100 feet from the display unit and have not had any issues with the wireless range. The wireless signal indicator showing strength of signal is a good feature. Another good feature is the two low battery indicators. One for the outdoor sensor and one for the display unit. Love the posting of the high and low temperatures over a 24 hour period. Excellent user support as I was able to clear up one issue within two days over email. Great unit for the cost.

Nice sleek model. Works great! Definitely recommend.

Works well, it's accurate, and it's easy to set-up. I only give 4 stars because the outdoor sensing unit only lasts an average of 3.5 years. I've bought several through the years and I know this for a fact. The one I bought in Dec 2021 just died and will order a new one now in March 25.

Easy to read. Seems to be more accurate than others I have had. Works well from every place I have tried.

I replaced a 20 yo similar thermometer with this one. The main difference is that it doesn’t announce the temperature which is better because after being silent for many years it started after the batteries were changed. We couldn’t shut it up. This new one is easier to read at distances. It is a little smaller but is a good size and a good value. I can’t say anymore than that since we’ve only had I about a week.

Great - it works great and keeps temp and time accurately. This is the second one we have had in 5 yeaers

[the model number on the front of the AcuRite instruction manuals is 00424M, while the model number on the back of the outdoor sensors is 00606TXA1. Confusing? I certainly think so! Something feels screwy about that! Why don't the manual and sensor have the same model number?!]I bought the first of my two AcuRite thermometers from Amazon in November 2024, but didn't notice until the recent cold snap (I live in the PNW) that my outdoor temperature readings were off by 4 degrees. I returned the first sensor/receiver pair last week, and received the second sensor/receiver pair a couple of days ago - it also is off by 4 degrees for the outdoor reading. I have written AcuRite asking them if I should just keep exchanging them through Amazon Prime until I get one that works correctly, which certainly couldn't be profitable for either AcuRite or Amazon!* this incorrect sensor reading occurs, as far as I can tell, around 45 degrees. When I brought both pieces insides (both times), the temperature readings were the same for both the sensor and receiver. It's between 40-45 degrees that the 4 degrees differential appears.* I am using lithium batteries in the sensor, it's 8 feet above a wooden deck, and it's under an eave. I'm using the same nail that I have for over 5 years with other AcuRite thermometers.* I have two points of calibration: a Weather Underground weather station one block from my house, and the thermometer in my 3-year-old York heat pump.Up until now, I have always been very pleased with AcuRite. I wonder if they got sold to somebody?
