This one is a Zoo Med Digital Thermometer with probe. I've heard that many of the "reptile" thermomters are not all that accurate in the past, but a few friends had tested the Springfields I'd been using with temps guns, and they were usually pretty spot-on for accuracy (within +/- 0.5 degrees F). I wouldn't mind finding a fairly inexpensive thermometer/hygrometer gauge, but most of those are really pricey (~$25-30), and I hate to spend that kind of money if they aren't even accurate.

I'm trying to find something to monitor individual tubs in my in-the-works DIY incubator. I'm usually not very good at this DIY stuff, so I'm trying to see how well my little project is working. LOL I'm using an old wine fridge, taped in some heat tape, and hooked it up to a Spyder Robotics Herpstat thermostat. Just trying to monitor individual tubs now to see if a fan is necessary, or if all the tubs throughout are fairly consistent.
