Indoor Thermometer Room Temperature Home Hygrometer Humidity Gauge, Accurate with Calibration, Backlight, Air Comfort Indicator, 24H Max Min Records, Time, Date (AAA Batteries Included)

- Firstly, the humidity and temperature can be calibrated separately but wait a day or so until it acclimatizes to your conditions. - The most important information is represented in large numerals (2cm high, 1cm wide) while the time/date and high/low is smaller. Both are clearly readable from 15ft away. - The battery cover stays ON, unlike a report from someone else. - It has a convenient 45 degree fold-in stand and a pull-up hangar for wall mounting. Both are flush mounted and pull out when needed. - The LED is backlit after pressing the front light icon and lasts for 15 seconds each press. I never use the backlight feature as the display is so easily readable at all hours. - Really like the 24hr High/Low on Temp/humidity which resets at midnight. Let's me know the range of values for that day. It does not have a historical temp/humidity graph. - Any config buttons on the back are merely for "once set-it then forget-it" functions. No operation buttons are needed. - There is a color bar dividing temp from humidity and represents the current humidity (dry, comfort, wet). - This device is not meant to be used in a pool or a sauna, which would quickly destroy it, (as I think some customers did). - This device can be useful for indoor gardeners and anything else indoors. It's not really meant to be used outdoors where it can get wet. Although, the display is strong outdoors and doesn't get washed out by direct sunlight. - If the battery gets too low, all numerals turn to "8" and a low battery icon appears. You know what to do. What could be done to improve this product? - Sell it in black? - Make it strongly magnetic? I'm very happy with the product and will buy a second one after this review. Enjoy! Edit: Dec 2023, both units going strong. One in my bathroom, the other at my desk. Wonderful product.

Good size letters that hubby needs. Nice smaller footprint so it doesn’t take up much space. He likes monitoring conditions!

Works as stated, no frills

Average accuracy out of the box. It can be calibrated but each time you replace the batteries you must recalibrate. The display clarity is very good

This is the second one of these I purchased. Both units took a while (1 to 2 hours) to settle down and acclimate to the room temperature and humidity. The units' temps track within .1 to .4-degree F of each other and very closely match the room thermostat. The humidity indicated tracks within 2 percent of each other, both temp and humidity indications are well within the stated accuracy. My location is S. Florida, so AC is running most all year. I am surprised the inside humidity is so low (44%), however it is late October and for the first time since April, the weather is moderating. The units are readable, even in low light without the backlight, but the backlight makes the display appear just as the photo on the Amazon web page. I'm using the 2 supplied AAA Maxell Alkaline batteries in both units. Battery life is yet to-be-determined. At first look, these little units work great (one for1 week and the other for 1 day). And at $14, are, to me, an exceptional value for what they do.

Works well

Nice, affordable temperature monitor. I use it to track food storage and the high/low history is great.

The unit drains batteries very fast (maximum 2 weeks) and worse still when you install new batteries (I used rechargeable models tested to retain full charge), everything gets wiped out. You have to reset the date/time, etc. Terrible that they didn't implement a memory function for the basics. Other than that, Iit is amazing how long you have to search to find anything weather and temperature related that check all boxes. I haven't found any that can be customized for essentials and feature bold big display. So I came across this that does the measuring for two things very well; temperature and humidity. Tracking the lows and highs for the past 24 hours is a very useful feature. It allows me to see how cold a space gets over the course of the night before. Same thing with humidity. It come with a graph showing the humidity range as well in terms of percentage that translate to comfort level. Low humidity during winter can contribute to cracked lips and other issues. I also use these to monitor parameters for a room my parrots are kept. These displays are prone to permanent dark spots over time. I will update this review after a period of use to see if this model is like the other ones or not. The other issue is that I am not sure where the sensors for the unit are located. It comes with an option to hang it from a wall, which I'm planning on doing. Hopefully the contacts can read an accurate temp. in close contact with a solid wall. I'll run some tests and update this review and look up the manual to see what it says about proper placement. The other huge plus is that it works with rechargeable batteries. I hate having to keep investing in one time use batteries that even if recycled, which I do, still carry an environmental impact and cost a lot. I use my rechargeable batteries for this and it works great. Any model with built in batteries are also meant to be disposable as the battery will eventually stop holding a charge rendering the unit worthless.

Just received this item but loving it so far. Having the option to light up the display is a huge upgrade from the last one we had. So far it’s five stars from us.

The devices seem very accurate, at least in-between several of the same (I got 4), and at least as far as the temperature is concerned (I compared them with my central thermostat's thermometer). When left on the table together, the differences in temperature are within 0.3 degrees (oscillating up and down, rather than fixed, so at times they are basically showing the same), and in humidity within 2% (same comment about up and down), which I find very acceptable. No cons, really. Could have they been cheaper? Probably. It's worth it, when they do the job. I cannot comment on durability, as I got them recently. The seller seems eager to help, however I haven't needed this so far.

I got this thermometer to use in my basement to monitor air temperature and humidity as the thermostat is on main floor and feels cooler and more humid in the basement also want to adjust the air flow to balance out the house. This unit is precise, tested on main floor and compared to furnace thermostat and HRV unit, then moved to basement, found huge difference in readings. After playing around a few days with the registers, I got a close enough balance. This thermometer helps and works well and is accurate as is but is capable to be calibrated to read as per other thermometers or existing thermostat. The package included 2 batteries type AAA and instructions that are easy to read and fallow. The initial setup was very easy and straight forward with large press buttons on the back side to set Celsius or Fahrenheit, time and date. On front side has a touch button for night light to see the screen. Also, I liked that has an option to hag it on the wall so I can place it not central in the house instead of just resting on a table. The only deficiency found on the unit, was the battery cover, it doesn’t click in to stay closed and tends to fall off. I fixed that with a small piece of clear tape. In rest, good product and good price, I recommend it. Thanks.

Came immediately and it is well designed.

Great product overall. I bought it to measure the differences in temperature & humidity between our living room and bedroom and it has impressed. In fact, it worked just as good (if not better) than the existing digital thermostat we already had in our bedroom that I moved the old one to the lower floor. The umbers are easy to read in the daytime and the backlight makes it easy to read at night. The only thing I wish it had was a proximity sensor to enable the backlight without having to push a button.
