Before you get it , buy a digital thermometer hydrometer dont use the thermometer that comes with the unit is useless
to test your new hydrometer
you will need
1 ziplock bag
1 ceramic cup
1/2 cup of sea salt
1/4 of water
put the salt in the cup
put the water in the cup
put the hydrometer and the cup inside the ziplock bag
close the bag , and wait 12 hours ,it should read 75% humidity if is higher or lower than you know how to read your humidity in your incubator
when you get the incubator
put it toghether and run it without water put the thermometer hydrometer inside to findout how is ur humidity in your house after 24 hours you should have a good reading of temperature and humidity
than add water
I put 1/4 of a cup of warm water and wait to see how much will that increase
if you need more add another 1/4 of a cup
and wait
dont spect the reading to change fast it takes time
hope this helps
I have one 1588 with turner running now with 44 quail eggs
