I searched the internet looking for an economical thermometer to keep track of the heat on my seedlings. These thermometers I found here are just what is needed. They are the perfect size to sit alongside the grow trays and are very accurate. The price was fantastic and shipping was very reasonable. They arrived when quoted. I'll be back for any additional needs and will alert my friends in the Chicago area.
Cant beat the price! Came with 2 extra batteries also!! Works like a charm!
Needed a cheap thermometer to peek at my tub without taking the lid off, i ran the probe right through the air exchange hole and used double-sided mounting tape to stick it about 1" above my substrate and I found out that I had it too warm! Very accurate and easy to read!
My new probe thermometer is great. So much better than my old, non-probe one which I could not leave in a grow tub for very long before it would fog up.
Have not used yet but appears to be functional out of the box. Like the long probe which enables you to secure temp device exterior to grow chamber.
