GQF digital Hygrometer. Made in the USA.
Accurately measures Humidity and displays it as a percentage. Easy read LCD display. Includes transparent plastic base to allow placement directly on top of the eggs for more accurate readings. Unit does display temperature but as with all digital Thermometers they are not calibrated so the accuracy of the temperature reading has not been tested.
Note: I use one of these for a thermometer and when checked against two other thermometers it is reads the same, but as they are digital and not calibrated we prefer to sell them as not being tested.
