We use it when camping and hiking long distances to help us stay on top of the temperature especially when out of cell range.

Also helps us choose the best clothing/layering options.

Easy to use and easy to recall data when needed.

I am on a federal team for disasters and I have one of your weather stations. It's great. My wife shows dogs so made this purchase so we could keep watch on temperatures on the in side of the van. I am disappointed in the lack of range. Can't even get a reading from my garage (attached) from our kitchen .

Easy to use, seems durable (at least after one month of outdoor use).

Works exactly as promised
Great product. I first tested one in the refrigerator. To my surprise I was able to access the sensor through the closed metal door. There was plenty of signal through the refrig. gaskets. The data is very easy to DL and forward to my computer through email. I keep one sensor in a cooler in my car. It slides and rattles around as I drive. So far the sensor works flawlessly. Recommended.

what's the temperature range

Hi, the temperature range is 14 to 131°F -10 to 55 °C.

I need a product that will stay in solution of 90% water and 10% alcohol, and will be used to measure the temperature curve of a product in tank trucks. Which product you have to offer with connection wireless or Bluetooth.

Extreme Meters LLC.

Chemical immersion is not advised for the DROPs, so I cannot guarantee they would work in that situation. The alcohol could have some damaging effects to the unit but this specific case has not been tested. For the other question, it uses Bluetooth.
