    Dual display.

    My TH-1 meter worked well for about two years. Unfortunately, the hygrometer is now in a constant error mode (E11) asking for calibration, which costs 650$, almost 10 times the value of the meter. There is no way to get rid of the error and keep using it. GARBAGE!

    ✘ No, I do not recommend this product

    I purchased one of these and it failed within 30 days. Two months later I received the warranty replacement and it failed that same day ( the second time I pushed the on button). I’ve always had good service from Amprobe meters, including humidity, but definitely won’t own another TH-1.

    ✘ No, I do not recommend this product
