I bought a separate thermometer and hygrometer that both had a money back garantee that they were accurate for incubating (thats what they were designed to do) and I compared the combo temp/hygro reader that came with my bator and it read exactly the same as the garanteed ones
it has 'incubatorwarehouse' written on the top of it so if I ever needed another one I'm guessing I could buy it from them online. It really helps to have accurate equipment, hatching chicks is hard enough without dealing with bad readings (like it did with my first hatch).
