My Digi-Cab dial hydrometer was indicating about 70% Humidity. However my digital hydrometer from Muji indicate 35%. Not sure which one is more accurate. Any other way to calibrate the system?
I was also worried about accuracy, so I bought a Digital hygrometer from HOmeFix for abt S$30. It turned out that the reading from my dry cabi was 10% lower than the hygrometer. I adjust to an average of 45% between the two.
