Temperature sensor incubator correct placement

[aseel lover]

Where should temperature sensor placed in incubator ..i am facing problems that temperature inside incubator doesn't match with temperature sensor of hygrometer

Initially, I place all sensors side by side as close together as possible so I know if they read the same before I try to determine how temps vary in various locations.
Keep in mind that all thermometers will have a different response time. Some are instant read while some may sample every minute or longer.
You'll need them all in the same spot for several minutes with the incubator closed to level out the differences in sampling times.

Put them at the level of the eggs. You’re going to want to make sure your thermometer and hygrometer are calibrated correctly. That can be the cause of different readings. If you have a still air incubator there will be some parts of the incubator that are cooler than others as well.
