I’ve recently purchased the humidity controller as I’ve had only minor inconveniences and vastly positive experiences with the thermometers before.
The humidity controller is completely inaccurate though. Usually when users have problems, it’s because the probe is wet and it shows higher numbers than the actual humidity.
Mine is the opposite. I’ve changed positions, I’ve reset it, I’ve used it in different places. No luck.
I’ve verified the actual humidity with three different readers, all which show 80-85%, while in the same position the IHC-200 always shows around 60%, which makes it almost impossible to use it for the intended purpose.
Hello,
Could you please use the salt method to test it?
Please put the IHC-200-WIFI probe inside the baggie.
Here are the details:
Gather supplies. To test your hygrometer using salt, you just need a few household supplies:
A small food storage bag that zips
A tiny cup or bottle cap from a 20-ounce soda
Some table salt
Water
Fill the cap with salt and add enough water to make a thick slurry. Don’t add so much water that the salt dissolves; you just want it to be wet. If you add too much, use paper towels to mop up the excess.
Put the cap and the hygrometer inside the baggie. Zip it up and place it somewhere out of the way, so it won’t be disturbed during the test.
Wait 6 hours. During this time the hygrometer will measure the humidity inside the bag.
Read the hygrometer. If it’s accurate, it should show a humidity of exactly 75%.

Can it read 75% after 6 hours?
If its readings still deviate significantly, please contact the seller/email: support@inkbird.com for after-sales.
