Ive never really thought to ask, but thought i would so to add to my incubator education. Is there an optimal place to set the thermometer in older LG 9200s (or any model if its all the same)? Im down to 1 thermometer (mylar backed glass type) i trust for each incubator. I assumed place the mercury ball midline between heater and middle, but thats a pure guess. Below is a pic of my placement. Ive placed computer fans in the fan location, but assume its still a still air unit since i havent determined how well thats working out yet. Please indicate a position by the mercury ball (sorry not sure exactly what its called) at base of thermometer)...the whole thermoter takes up half of one side. If possible, throw in a pic of proper placement if thats easier than describing it? Thank you!
