Caliber 4R Hygrometer

Great so far. Only complaint would be that it hard to see unless your eye level with the display. But I am happy with the product and it’s accuracy.

Accurate so far. Nice compliment to my humidor.

Purchased to confirm accuracy of another hygrometer; it is excellent and with the BOVEDA, I have no worries with the RH of my humidor.

Bought one several years ago to replace the one that came with a new humidor. It worked great for about a year but the just stopped working. I replaced the battery but that didn't help. Now using several different versions, in multiple humidors, and they all seem to be working fine. Don't know if my failure was a fluke but I just though it was a good idea to pass along my experience.

Have a large humidor, needed a second hygrometer. CALIBER 4R is a great product.

Works great and looks even better. This is by far the best looking hygrometer out there.

Great help in maintaining correct temperature

Super easy to read, accurate hygrometer.

This hygrometer paired with Boveda packs is the perfect combo for giving me peace of mind that all is proper & right in my humidors. I also like that the tight +/- 1% of the 4R

Accurate and easy to read.

I have tried many different Hygrometers and this is by the best that I have ever used. I will probably pick up a couple more so that all of my vessels have one in them.

Accurate

Looks great and works great, very accurate.

Works perfectly. I needed one that was more accurate than the one which came with my humidor.

I think it looks great but the calibration appears a little off. I recalibrated and shouldn't have to buying a new device.

Best hygrometer I have ever had

Looks good and accurate, calibrated with my Bovita Butler and it's right on....

The display is very nice. Kind of old style meets new style. Accuracy is very good and it keeps good temperature.

This hydrometer is accurate straight out of the box. Unfortunately the display is tragic. You need to be eye level with this thing to read the meter. The way my humidor sits on the mini bar makes it so I have you squat down to see the reading if I’m putting it right under my humidor lid. Looks are completely secondary to functionality for me. The cigar oasis or western caliber 4’s are far better with my set up. Very accurate and a clear display at all angles. I am sure others must find the lacking field of view annoying with the caliber 4R. I am sure this item will be great for someone’s different humidor placement. But it simply doesn’t work for my particular set up.

Very pleased with hygrometer. Keeps accurate readings for my 50 stick humidor. Would buy again but hopefully won’t need to!

Is working as advertised.

I’m still trying to figure out how it works

Does what it's made to do, good price.

Needed a new hygrometer for my humidor. This had the added bonus of showing the temp on it at the same time. It has helped save my cigars.

GREAT

Easy to read and accurate

Ladies and Gentlemen, This is the one! This is it! Do yourself and especially your cigars the favor and drop this in your cigars humidor. Spot on accuracy right out of the box. No problem reading the instrument through the humidor glass. Bought three of these and right out of the box all three passed several salt and other tests with the same exact results, no calibration needed, although available. Bought another one today. I finally have peace of mind knowing that my cigars humidity and temperature are accurately monitored. Great product! Thanks CI!

Its was easy to set and I'm very happy with it.

I’ve had them all, this one is deadly accurate right out of the box ! Great product.

I have tried many different types of hygrometers and this one is the easiest and came out of the box very accurate. I really like this model and will buy more.

Very accurate, very satisfied with purchase.

Working fine. Way bigger than the analog though.

Best hygrometer very accurate highly recommended it very happy with this product ??

Excellent

Best one I've ever had, simple,easy, and accurate!

Works as advertised. All prior reviews were no exaggerations. If you want a hygrometer that reports accurate information, at a more than reasonable price, this is the one to get.

Works like a charm. Highly recommend drop this in your hunidor with boveda pack and your golden.

Works great! Accurate an affordable

I have two of these now as back up to the built in units. These never fail me. They come out of the box ready to go all you have to do is put the battery in.

The magnetic mounting system is great. I’d give it 5 stars but I’d like to see the magnet a little stronger.

Works well

so far so good we shall see how long it works

well done

Have been very pleased with it. Looks great in the original spot in the Humidor as well. For the price I recommend it for sure

Works very well and somewhat consistent. A good buy.

I put it in the humidor and left it for a while. Went back to check it and it read 72/73.......Close enough for me.

Fits perfectly inside humidor. Affixes to door of humidor with tape. Works real well. Pre-calibrated. Don't put directly under the humidification if you are using bead jar. Move it to a corner away from humidification and it will work just fine.

Wow battery in and set way too easy to use :-D. I couldn't believe how fast it worked, I set it, read it and not worry about my cigars as much as I did before. Now my hubby and I can just enjoy. This was an amazing buy it was packaged well also.

It's super easy to use, I was surprised to see how accurate it was emmedatly. And it came with a battery too yay! This is a must have for ever humidor.

Looks awesome in my 150 count desktop humidor. Accurate and easy to read! Easy to calibrate with a simple Boveta packet and a ziplock bag test. This is a great alternative to using the analog style that comes in most desktops. I'm very happy with this product and its helping me maintain my Cigars!!
