2" dial for easy reading. 3 1/2" stem can be inserted in 5/32" hole to permit reading of temperature from outside of the incubator. Standard equipment on older GQF cabinet incubators. Can be used in Hova-Bator also. A wick is supplied to be used as a Hygrometer by mounting a water bottle below the tip of the thermometer. Slide wick about 4" on to the thermometer stem and immerse the other end in water bottle or pan for wet bulb hygrometer reading. Be sure to keep wick clean for most accurate reading. Extra wick can be ordered also.
