Hatchaholics seem to be the right group of people to help me with my question.
I have eggs in my brinsea mini advance. I have done 2 hatches in it before this one and I determined that the temp on it was about a degree low, the first batch set at 99.5 hatched on day 23 and the second hatch when I set the incubator to 100.5 hatched on day 21. The directions say to fill 1 of the 2 water chambers on days 0-18 and then fill both for lockdown to up the humidity. I have 2 different digital thermometer/hydrometers that I got from incubatorwarehouse.com, one you put into the incubator and the other has a probe thing that goes in and the part with the numbers stays on the outside. When I filled just 1 chamber they both read the humidity around 55%, I tried to get it down by covering the chamber with a tissue and 1 says it's 25-30% and the other says 10%. Also, both meters give me drastically different temps (98.8 and 97.0). Should I just toss them and get a new one? I've only used one of them once and the other twice. I also have one of the glass thermometers that came with my hovabator and that only has marks for 98 and 100 and the line was somewhere in between so it could be 99 or 99.5. What do you guys use?
