AcuRiteAcuRite 01080M Pro Accuracy Temperature and Humidity Gauge with Alarms, Black

When I was fighting a humidity issue in my workshop, I realized I couldn't solve it without monitoring results - and picked up a SensorPush Wireless Hygrometer with Alerts for that purpose.It quickly became apparent that, although the SensorPush is awesome, I wanted to be able to see the humidity at a glance when I'm out there - so I also picked up a ThermoPro TP55 Digital Hygrometer that I could just stick to my gun safe using magnets.If I hadn't been using the SensorPush, I probably would have been happy with the ThermoPro - but I did have a couple of issues with it:1) The humidity level didn't match the levels from the SensorPush - which was driving me nuts.2) Even when the SensorPush reported wide swings in relative humidity, the ThermoPro seemed to stay stuck. It was always reporting 48-52%, even though the SensorPush reported a far larger range.After a couple of weeks, I came back to Amazon and picked up the AcuRite 01080 Hygrometer - which turned out to be an excellent decision.1) The readings on the AcuRite are FAR faster, so it reports the same swings as the SensorPush.2) The AcuRite supports calibration (which I did using a Boveda One-Step Calibration Kit). It's a little hard to calibrate the Acurite inside the Boveda bag; but, only took a few minutes using the button map from the instruction pages. (The problem is you can't see the buttons - you have to feel for them.)It's interesting that the AcuRite was off by almost 5% out of the box - but now it matches the SensorPush (which is also calibrated) perfectly.After reading reviews, I almost didn't buy the AcuRite because of complaints about the display contrast and size. Personally, I don't see the issues at all - it seems plenty big for my purposes; and, although the contrast definitely isn't as good as the sticker that comes on it - it isn't bad either. The contrast is pretty much comparable to any other digital display.If you're comparing the AcuRite vs the ThermoPro, the ThermoPro has an easy-to use touchscreen and backlighting, while the AcuRite seems to focus more on being a good hygrometer.If you're going to be constantly switching back and forth between Celsius and Fahrenheit, or want a backlight, then consider the ThermoPro - otherwise just grab the AcuRite, it really is an excellent unit.[*** Update 12/12/2017 ***]This has worked so well that I ended up getting another one to track the humidity by my main gun safe. After letting it settle for about 8 hours and calibrating it - it works just as well as the first and tracks the other sensors perfectly.

Easy enough to read, especially the humidity (can read that from 15 feet away as long as a light is on).Also working well with AAA eneloops (so far only had it for 2 days but looking really like it's ok)If want to adjust the humidity to a specific setting, after making the change give if a minute or two tosettle in to the new setting. If you missed your mark do again. I got it in second try. Don't forget it hastenths of a percentage reading (but not tenths adjustment). I haven't yet set a humidity alarm but intend to later on.

*Important calibration note in this review!*5 stars for everything because, it's a hygrometer: it's supposed to measure humidity and that's what it does.It also reads temperature, shows maximums and minimums for temperature and humidity, and has a digital bar at the top with an arrow that points to humidity from zero to 100% (technically, the instructions say it has a humidity range of 1-99%). Runs on 2 AAA batteries. Can stick to fridge by magnets on the back. Can stand upright on a table using the magnetized stand. This hygrometer can be calibrated and I calibrated mine with the “one-step calibration kit” also bought from Amazon. Now, either I was lucky that I received a perfectly calibrated unit out the box, or AcuRite simply delivers on accurate hygrometers. You can get a hygrometer from Walmart for like $10, but I was willing to spend a little more for accuracy, and I think the price for this unit is worth it. Either way, please read my note on calibration below.CALIBRATION AND ACCURACYCalibration may take some time! I think any negative reviews come from people who may not know how slowly moisture content changes, especially with calibration. The calibration kit says to keep it in the calibration bag for a minimum of 24 hours. I highly recommend keeping it inside for longer.Straight out the box, I hung the meter for a day and it read somewhere between 60 and 65% humidity in the house. I put it inside the separately bought calibration bag that calibrates to 75% humidity. It took 3 days to get to 71%. I almost took it out and calibrated it up 4 percentage points (to 75%), but I kept it inside. Next day it read 72.8%. Since it was increasing, I thought to wait and see how high it would get. I ended up forgetting about it and four days later it was at 74.9%. That’s when I took the pictures with it still in the bag. Upon moving the bag for the pictures, the reading fluctuated to 75, 75.1, then back to 75. But I mean, you can’t get much more accurate than that.THE POINT IS THAT IT TOOK LIKE A WEEK TO CALIBRATE EXACLTY TO 75%, so that’s why I recommend leaving your hygrometer to calibrate for longer than a day, and wait before writing a bad review for a “bad” hygrometer. Moisture is a fickle thing, unlike temperature. (Although, you probably won't even need to calibrate yours. AcuRite makes pretty good products).So 5 stars. Accurate for temperature and humidity. I compared with an old $10 hygrometer that I had and they read the same for temperature and humidity after calibrating the AcuRite.

Functions great - easy to use - seems accurate. The magnet is so strong. It's a very cool instrument and I adore it. This could easily be a 5-star product BUT gets 4 stars because the display is inexplicably dark and gray. It makes no sense. You can't really see it in the dark and you can't really see it in the light. If you tip it 45 degrees it's ok but when it is flat in its stand or on the fridge or lying down you can't see it very well. So many reviewers have remarked on this--the company really should fix this.

I recently got a split air conditioning unit for my TV room and I wanted to monitor the humidity and temperature. I saw this item and decided to try it and I absolutely love it. It has a large display that's easy to read. I was able to hang it on the wall, although it does come with a table stand and it's extremely accurate. The price was right and I'm very happy with it.

More than a year later, this humidity monitor is still functioning well, and hasn't let me down. Unlike other monitors I've tried, this one was far more accurate straight out of the box. I had a Honeywell monitor that was never accurate, could never be adjusted for accuracy, and died completely inside of a year. I've never adjusted this AcuRite monitor, though I should. I've only needed to replace the batteries once in the time I've owned it. I find it's just the right size - not too small that you can't read it, and not too large that it appears unsightly. At first glance, the price seems a little steep - but the fact that it still works over a year later has me feeling better about the purchase. Hopefully this trend continues.

Buscando una opción qué me permitiera medir la humedad y temperatura de una pequeña cava de vinos, encontré este higrometro.Me gusta la visibilidad qué aporta, así como un histórico de máximos y mínimos para temperatura y humedad, ya que me permite conocer la fluctuación dentro de la cava.También tiene una opción qué indica la tendencia actual, por ejemplo, la humedad se ha ido incrementando.Tiene una alarma qué parece util pero que decidí apagar.No sé si sea el más preciso pero para uso doméstico creo que es perfecto

Alles Okay

Very accurate on the humidity reading, & also on temperature. (Tested against my dehumidifier & separate monitor)The lcd figures react very quick to changes compared to my older monitor shown, & so more accurately depict real-time environment. Pretty impressed & the price was good 😌. I’ve been able to see the variations between rooms that we use & those that are not, & air them out as needed, getting rid of humidity & keeping other parts of the house warmer as a result.I’m pretty chuffed with these little beasts. I’ll buy another for the hell of it as I like to know which parts of the house seem more affected by moister, with 2 little girls at home, it’s a good idea to make the house not only comfortable for them, but eliminate any humid/temp issues that is known to affect health/respiratory etc. I’m happy, even if I’m a bit of a nerd for it 😅. Everyone benefits in the end ✅
