HUMIDITY
The LCD electronic control unit can perform the digital reading of humidity expressed in RH% (range 20-99%) and, if connected to an external
ultrasound humidifier, it is a super-modern digitally-regulated automatic humidification systems.
Generally for humidity, as already mentioned, it is enough to fill only one basin with tepid water and wait for 4/5 hours in order to see the value
indicated by the hygrometer. If the value is too low, it will be necessary to increase humidity with the addition of another basin of the same
size. If the humidity reading is too high, it will be necessary to reduce the water surface, by using a smaller container (or even no water at all).
It should be remembered that it is the surface area of the water which affects humidity, not the depth of the container or the volume of water.
During the hatching period it's necessary to fill all the basins supplied, 50% of the eggs have pipped.
Take note that at the beginning of incubation, the eggs contain 100% liquid and they do not need further humidity; when the embryo grows
at working temperature, it may* be necessary to give humidity because the internal liquid will evaporate.
The humidity reading in degrees Fahrenheit is shown by the wet bulb hygrometer. For conversion to % Relative Humidity (RH), please com-
pare with the table below.
N.B.: Note that the wet bulb hygrometer shows the lower temperature produced by the cooling effect of evaporation (in comparison with the
air temperature) and needs to be converted to % relative humidity (RH). For this reason if the bulb is dry it will show the air temperature (not
the humidity). Consequently it is necessary to check that the wick is always wet and correctly pulled onto the bulb. We suggest also checking
the condition of the wick, especially if in a hard water area, because the water calcification damages it and may cause an inaccurate reading.
Use of deionised or distilled water is recommended for wet-bulb use.

In order to regulate the humidity level inside the machine it is necessary to modify the basin's surface: enlarging the surface water
increases the humidity, reducing the surface area decreases it.

VENTILATION

Ref. MG140/200
The incubator is supplied with two air intakes positioned on both sides of the unit and one exhaust hole positioned on the upper panel for
carbon dioxide expulsion. For the control of ventilation, the incubator is supplied with a fan speed regulator which should be switched to
maximum position during the incubation period (put it on "incubation" position). The fan speed must be decreased during the hatching period,
changing the position of the regulator knob in an anti-clockwise direction to "hatching" position.
The ventilation speed will be easily manageable on the incubator model MG 140/200 featured by LCD control simply acting on the
main control panel, pressing the dedicated button.
When batch hatching, the fan speed should not be decreased for the hatching period, in order not to damage the eggs which are in incubation
phase.
During the incubation period, it is necessary to ensure the optimum oxygenation level, which will vary according to the number of eggs loaded.
The correct ventilation for a full load of eggs will, necessarily, be too much for only a partial load of eggs. The level of oxygenation can be
controlled by adjusting the diameter of the ventilation control placed on the left panel of the incubator.
ATTENTION: Never completely close the ventilation control because it would change all the values of temperature/humidity and
aeration, thus compromising the incubation results.
Ref. Mod. MG 200/300
The incubator is supplied with an air intake and an exhaust hole for carbon dioxide expulsion, both positioned on the upper panel.
