Best thermometer/hydrometer?

[Kymw90]

Which make or models do you find best to use with your auto incis? I have used one of those dial ones that have both temp and humidity on it like the reptile ones. Are these ok or could I be using much better ones that are still relatively cheap?

Re: hygrometers: There is info in a thread on how to calibrate them, or check accuracy. It uses a salt water solution. Re: thermometers: I used a medical thermometer because they are required to be quite accurate. Compared the reading to a large red dye bulb type of thermometer. Once you know how accurate your thermometer is, and how accurate your hygrometer is, you can make adjustments accordingly. ie: add 2.5 degrees to your thermometer reading, and add 10% to your hygrometer reading.

So do you use 1 thermom and 1 hydro and not those combined ones?
