Analog hygrometer recommendations

Post by Indaswamp » Tue Feb 09, 2021 05:24

Looking to add an analog hygrometer to y chamber. One that I can manually adjust with a screw on the back or by turning the plate to align with the arm. What do y'all recommend?

That's a good question. I tried three over the years and none worked for long. They were not built for a high humidity environment. There are high grade scientific grade hygrometers available, but they are very expensive. I currently have 2 controllers with wired sensors and one "weather station" with a wireless sensor in my chamber. I look at all of readings and from time to time, when there is a wide difference between them, I calibrate them all.

I've gone through 3 myself. Not impressed with them at all. I just recalibrated my humidity controllers using the 75% Boveda calibration pack. Both were off...-5.5% and +4%...
