I made my recommendation on your other thread and mentioned this one. http://www.petmountain.com/product/hygrometers-thermometers/11442-513304/zilla-terrarium-hygrometer-thermometer.html?utm_source=gcs&utm_term=11442-513304 but is has been proven not to be as accurate. Plus it will only give you one reading at a time and has no humidity readout.
