Egg Candlers and Scales

Candling and weighing are the best ways to ensure that your eggs are being correctly incubated, giving you the opportunity to weed out infertile eggs. This also allows you to follow the fascinating development of your egg as it progresses from yolk to chick.

A candling lamp has a concentrated beam that may be shone through the egg shell illuminating the contents. Candling allows the observation of the egg’s development during incubation and whether the egg is fertile or infertile. It also allows the size of the airspace to be assessed helping to determine weight loss and therefore the humidity in the incubator should be increased or decreased. If the air space is larger than expected humidity needs to be increased to reduce water loss, too small a space and the reverse is true. Egg weight loss can also be measured by weighing the eggs on the digital egg scales.

Thermometers and Hygrometers

To help you monitor conditions inside your incubator, our simple range of thermometers & hygrometers provide a great way for beginners to get to know the principles of humidity and temperature, and with a little practice, you may find that you are interested in one of our more advanced  digital hygro-thermometers, the simplest of these being the button type hygrometer. We can also supply the older type wet bulb instruments used in some larger professional incubators.

Hygrometers and wet bulb thermometers are used to measure humidity in incubators however they are not suitable for still air machines as they require air flow to produce accurate readings. The wet bulb thermometer comprises of two thermometers one of which is covered in a moist cotton wick. Calculations taken between the two thermometers allow the relative humidity to be determined. Our digital range of hygrometers tends to be more accurate as they measure the change of electrical resistance of the circuit within the hygrometer.

Thermometers are available as electronic or analogue with prices to suit most pockets.
