D'Addario Humidity & Temperature Sensor
Additional Photos:
The D'Addario Humidity & Temperature Sensor is a precision-designed hygrometer that digitally indicates accurate relative humidity levels ranging from low (under 20%) to 99%. Temperature is displayed in either Fahrenheit or Centigrade, ranging from -32F to 122F (-35C to 50C). The HTS includes a programmable set point, as well as a memory feature that indicates date/time of the highest & lowest temperature/humidity levels the instrument has been exposed to. Get one for each of your instruments. Its a wise investment to properly install and use a HTS and a humidifier in each of your instrument cases.

It roughly does what it says on the box. It tells you the relative humidity percentage and the temperature of the environment it's in (with limited accuracy). It can also tell you what day and what time it is.
HOWEVER.
This thing eats through batteries like an hungry ogre through a medieval village. Batteries last maybe 2 months, tops. There's no indication the battery is on its last breath except the humidity level always reading "LOW" and the screen diming whenever it reads from the humidity sensor, and then it just dies. It is also wildly imprecise. On average, the humidity sensor is more than 10% off and the temperature sensor 3 to 4 degrees Celsius off. One thing to note: the lower the battery level is, the less precise it becomes.
The build quality is not that great. There's no proper CR2032 battery holder. The battery just sits there against the contacts and is held in place by the cover loosely retaining it once it's closed.
At 40$+, I expect better accuracy and build quality, and for it to keep track of highs and lows for both humidity and temperature. It is outrageously overpriced for what it is.

So I’ve had this hygrometer for maybe 2 years now. As others have stated, after a few battery changes, the screen just … dies. Thick lines across the readout areas. For $41 I would have expected a lot better.

At first I thought this was inaccurate compared to older hygrometers I have but I checked it with a salt tank and the humidity was spot on.

I bought 4 of these, two are in the garbage already. Battery dies very quickly and when changed, all I get is a Lo% message, nothing else. Changed batteries again, now just lines along the bottom of screen.

I bought this and within the first week the battery had died already. I replaced it but it last maybe another week and the battery died again. So I replaced the battery again and all of a sudden I cannot set anything - it just blinks all the time. It's complete piece of junk. I definitely DO NOT recommend this product.

This humidity & temperature sensor works great. The temperature & humidity high and low readings are recorded into the memory, along with the date and time of the readings (only 1 high and 1 low reading). Easy to set up and the high/low memory readings can be cleared by pressing 2 buttons simultaneously.
