6-Pack Mini Hygrometer Indoor Humidity Meter Digital Thermometer

These mini hygrometers work great and are perfect for monitoring humidity and temperature in different areas of the house. I like that the 6-pack lets me place them in multiple rooms and quickly compare the readings. The display is easy to read, they're small enough to put almost anywhere, and the readings have been consistent between the different units. They're especially useful for keeping an eye on humidity levels and seeing which rooms may need better ventilation or dehumidification. For the price, you get a lot of value with the 6-pack. Simple, accurate, and they do exactly what I needed. Highly recommended!

I'll jump in with the pros and the cons. There will be some overlap. Pros: - A cost effective solution for knowing the temperature and humidity level. Considering you get six of these guys, it's an amazing buy. - Small and compact measuring approximately 1.875 by 1.25 inches. Numbers are easy to read with the humidity number being displayed most prominently. - Fairly accurate. Measuring them against each other on my desktop, all read between 68.7 and 69.4 degrees F with humidity registering 36-38 percent with one showing 36, three displaying 37 and two showing 38. I'd note I do have a small heater running at one end of my desk, so this to me falls into the fairly accurate for the price category. Cons: - No way to calibrate. - These were designed to clip into something, though I don't know what. There are clips on the sides of the units. - While they are free standing, there is no way to set them at an angle. - They do feel pretty cheap, so durability and battery life are questions I can't currently address. Recommendation? Yes, I think I would recommend them for simple, basic information. I intend to put a few of them into my seed starter trays to keep an eye on humidity and temperature when I start my plants, so who knows how they'll do in that warm, humid environment. But I'd order them again given my overall first impressions.

Yes, they were all running (from the factory) and yes, they all show different temperatures and relative humidity and yes, none of them match a real temperature/humidity gauge. BUT, once you know one of them is two or three numbers high or low, it is consistent... it will always be wrong by the same number!! So they do work and they are accurate... they are just NOT calibrated with anything in the real world or with each other. As long as you remember "Temp is +2 / RH is -3" or whatever (and don't get them mixed up), they are worth what you paid for them.

Worked better than expected! Inspector said they read accurately and did their job. Highly recommend if you’re needing to capture humidity levels.

I got these to keep track of the humidity where I store my 3D printing filament. I don’t need them to be precise, but they seem to be accurate enough. They’ve been great for that. I have one mounted in each desiccant box, which has been working really well. The display is easy to read. I didn’t buy these for the thermometer, but I do like the added functionality. Just for fun, I put one inside my car. I did learn that the display stops being readable at about 132 degrees. But 2 months in so far and all of them still work just fine. They seem to be a pretty decent value.

A couple read high but all and all work well.

Fast changing, extremely sensitive, and in tight sync on humidity. I bought 18, and placed then in a row across my work bench. After they settled in, they were within 1% of each other in a very interesting way... You could see waves of change, if one went up by 1%, usually it's neighbor would, and that would ripple across the line. Or there might be several waves sweaping from an end and the middle... It was interesting to see that they were all responding to the environment in sequence with the neighbor. This tells me they are quick responding and fairly sensitive. I am in an extremely dry environment, with humidity artificially increased by a swamp cooler, so I am testing the low end of the range, 20% to 30%. If your humidity dwells higher, you may get different results. These type of i9nstruments are more accurate at 75-85% than they are down where I use them, so accuracy is not pertinent in my use case, Instead I will be using these as a quality of storage indicator and alarm, so when I pull a roll of 3 year old nylon down, I can tell if it needs a 2 hour dry cycle or if it needs days more. A "freshness" indicator that I can read without opening the package. Humidity was within 1% of the units neighbor. However temperature was closer together, but the fractional degrees were all over the place... Most of the temperature sensors are closer than the humidity, but because the temperature scale is hundreds of points in either direction, the temperature looks like they are a little father apart, but really they are as close or closer than the RH%. The quality of the sensors are very high to all be in agreement, but these are too cheap to be calibrated, if that is important to yo, do some testing with a calibrated meter. I have a wet bulb and a calibrated meter in the shop, but like I said mine are not being used in a way for best accuracy, but these seem surprisingly high quality so I suspect accuracy is either very good, or at least very repeatable and consistent. These are the best I have tested so far. I will package these with sealed and dry filament, and the levels read will be wrong... Th

Great buy and exactly as advertised. Also, Fast Shipping
