🌡️ 4 Pack of Ambient Weather WS-03-4 Compact Indoor Temperature and Humidity Monitors Review

A great find for showing the ambient temperature AND humidity level of your guitars when in their case or hanging on the wall! I bought this because I have a Martin acoustic guitar with a crack just below the pickguard. I'm pretty sure it has to do with sitting in my suitcase in August waiting for the stage to finish and final details to be worked out. This caused a delay of almost four hours and the temperature rose to 101 degrees! It also reminded me why I don't like doing outdoor concerts in

I bought this along with the humidifier so we can determine what humidifier settings to use when our oven is running. Two AAA batteries are required, which are not included. So if you buy one, make sure you get the batteries too. It does everything it promises and works great. It has a hole in the back so you can hang it, so we installed ours next to our electronic thermostat and found it to be room temperature. I would recommend this device to anyone buying a humidifier to help you understand…

In this group of four, I found statistically significant differences in scores between the four. The temperature readings are very similar, with a difference in the relative humidity (RH) readings. The group was tested in different places in the room and almost next to each other for 24 hours. The readings were inconsistent within the group and differed from the other device used (EXTECH 445703). , Units are useful. I don't need accurate readings of humidity or temperature so I'm not…

My weather thermometer was sent in a bubble envelope. After reading the instructions and putting the batteries in and making sure the polarity is correct, there was no image on the screen. I checked the bubble wrap that was placed inside the box when the thermometer was packed at the factory and found that about 80% of the air bubbles were broken. Since none of the vials in the mailer were punctured, I assume the device was overweighted at some point prior to shipping; enough weight to damage…

Positive or negative deviations can be annoying until you understand why they occur. I bought a pack of four, batteries were not included, put my different ages in it, then put all four in an empty tissue box and covered. On the way to the crate, I noticed that both were already close in temperature and humidity, the difference was no more than +/-2. An hour later the temperature was still very close. After a few days, all four are +/-1 in the 51% range. I have no idea how accurate that is, but

I received these babies knowing that their hygrometers would not be very accurate and I got exactly what I expected. Pros: They are very cheap in this kit. They also have a nice, small footprint. Temperature readings are very close. Well within the range they state. Cons: The hygrometer is more of an approximation. They give you an idea of what your moisture levels are. My house has forced air heating with no humidifier, so it's very dry in here. They'll say we're somewhere between 10% and 25%,

The part that reports humidity is a bit uncertain at lower humidity. My house got very dry last winter and I bought these along with a humidifier. About 10 minutes after powering up, three of the four were in sync to be within 2 degrees and a 5% humidity difference of each other. That's what the manufacturer says, that's the range they can vary (if you want something more precise, you also need something more powerful and therefore more expensive). Fourth, even though his temperature was within

So. There is good and bad in this device. I'll end up returning it because it's bad, but it might still be for some people. Overall, though, I would recommend looking elsewhere. Pros: I like the size. It's small and compact, perfect for lying in the corner of a humidor (in fact, it fits perfectly over some of my sticks and a box). The temperature is also accurate to 1 degree. Large numbers are easy to read. There is no backlight, but since I don't look in the dark, that's not a problem either…
