One thermometer or two?

[chrid16371]

I use acurite 00891. I put probe on hot side and run the wire under substrate to cool side and set unit there and from the one screen it gives me hot temp, cool temp, and humidity. They are very accurate and give me the same readings as me Herpstat and VE thermostats.
