Q
what is an aspirated screen thermometer?
A
the thermometer is shielded from direct sunlight so prevents false readings for the whole GH environment.
it is an insulated box painted white on the outside to reflect sunlight.
An electric fan draws air over the thermostat through an opening at one end of the box so we get a precise ait temp reading.
