Diary & Notes ~ Air Cell Detatched SHIPPED Chicken Eggs for incubation and hatching

I really like my probe thermo hygro but the hygro dont work, its like 30 off, I am wondering if I am using it correct. I just have that flat end sitting in the bator and the probe is in a salad dressing cup with water sealed up

Sally, Good morning..... I'm not sure if that is a question.... Humidity probes "usually" need a cotton sock around them... specifically cotton... a 100% cotton shoelace will do.... Insert the probe into the hollow core of the shoelace..... the water needs to be distilled so there is no interference from dissolved minerals..... The water wicks up the "sock" and the wet sock will evaporate water at a rate dependent on the humidity and evaporation rate.... Then "evaporative cooling" will be reflected in the temperature measured on the thermometer that the sock is installed on..... It's the same principle as a "swamp cooler".... a certain amount of "sock" needs to be exposed above the water dish..... and the sock need to be completely covering the measuring point of the thermometer.... I would guess about 1" of sock needs to be exposed above the water source... too close and wicking water speed will not allow the evaporation to take place properly on the therm..... too much exposed and the water may evaporate before it can cool the thermometer measuring point......
All of this info is directed at therms and not humidistats or what ever those electronic gadgets are called..... any therm will do.... evaporative cooling affects all therms the same... it's like the wind chill factor....

~Psychrometers (Wet and Dry Bulb Thermometers)[edit] 1861 diagram of a psychrometer with wet bulb (a) and dry bulb (b). The wet bulb is connected to a reservoir of water. The interior of a Stevenson screen showing a motorized psychrometer A psychrometer consists of two thermometers, one which is dry and one which is kept moist with distilled water on a sock or wick. The two thermometers are thus called the dry-bulb and the wet-bulb. At temperatures above the freezing point of water, evaporation of water from the wick lowers the temperature, so that the wet-bulb thermometer usually shows a lower temperature than that of the dry-bulb thermometer. When the air temperature is below freezing, however, the wet-bulb is covered with a thin coating of ice and may be warmer than the dry bulb.

I do have the probe in a small egg size dish but its in the water, I think the probe is temp? so it gives me the internal egg temp
the other flat thing with some holes I think is the hygro, so you think one like this gets the wick treatment? I didnt think so but I havent a clue!
I have always just had my accurites without probes so this thing is new to me.

This is the unit... http://www.amazon.com/gp/product/B00ADSRFVQ/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

below you can see my rigged probe in the salad dressing cup of water, but the other part is just laying in the bator

Hi Sally,

While the information that Dave supplied is good, it applies to a standard hygrometer and does not apply to these digital hygrometers. The problem with most of the digital hygrometers is that they most often do not register as what the actual humidity is. The one that you are using will not register below 20% humidity no matter how low the humidity gets.

The one that I am using has a separate unit that is for outdoor readings and that has a pretty good amount of mass to it. I place the remote sensor in the incubator and that sensor houses both the temperature sensor and the humidity sensor. It wasn't an expensive unit and the temperature read out is only in full degrees. Experience has taught me that when temperatures are right in the incubator the read out will mostly stay at 100°F with brief occurrences of 99°F or 101°F. It will only read humidity down to 16%.

Here is a link to information on digital hygrometers.

A video demonstration of how to calibrate a digital hygrometer. I am sure your model does not allow for calibration but it will allow you to verify if yours is accurate at the 75% measurement and can provide you with an offset value for your actual measurement.

Good luck,
Bob

I guess I should have taped that end up, I had so many chick hatch in the bator this time that hyro part got pooped on with green poop

It was safely tucked so I thought but those little wfbs rampaged the entire cooler, had to cover the fan with wire as we almost had scalping! They were standing on top of each other,

Note to self, even thought the eggs fit in for lockdown, perhaps its not enough room for hatch when the components are so close, I wonder if any burnt on the lights. I wish they would have popped out during the day so I could grab them for brooder sooner. oh well another lesson learned.

Guaranteed under those conditions the probe did not have any chance of measuring the humidity. My understanding is that the digital hygrometers measure the moisture in the air so the probe should be suspended in the air and not touching anything including being crapped on by chicks. Better luck next time.

I have a little chick remaining in the bator, a late hatch and in turn has a leg that is going outwards, so I put him in a peach Gerber Baby food container


"Me thinks" I will name him "PEACHES" HA HA HA

Just candled my eggs!! The local ones have great veins! I was also sooooo excited to see 5 out of 6 of my shipped also have veins!!! Their air sacks look pretty good too! The one egg looks like it may be a blood ring I took note and will check it in a few days! I'm so happy they are alive in there!!
