Topic: Out Humidity readings VS inside scensor

[Blizzard]

As many of you, my humidity outdoor scensor as started reading low (WRM 968). So far, if i compare with the closes metars, it probably has a 11% low reading, which can be adjusted with the off set. Yes, I'll check for spiders before 

My question is: As any of you tried to establish their low reading using the inside scensor? Otherwise, is worth buying a new scensor?

Thanks

What do you mean, use the indoor temp/hygro/barometer for the outdoor readings?

You could put it outside to test for a bit, but it can not be used to report back to VWS as an outdoor temp/humidity.  Its also not weatherproof.

You are probably better to either replace the thgr968 or get an additional sensor and do the channel 1 flip...

To get mine closer, I put out 4 different digital humidity sensors, averaged them, then took that average and adjusted the calibration in VWS for the Sensor to match that (+10).  I still have a channel 1 humidity sensor outside reading, that seems more accurate.  So I compare the two once in awhile. 

Funny thing with the thgr968 sensor......in regards to humidity, it reads lower than sensor channel 1 when temps are low (30-50) and higher then sensor channel 1 when temps are higher(60-80).   (50-60) seems to be the spot when they are both are close.  All of this of course still having the calibration applied.  I figure if I am within 10% of all the other PWS in my area, I am doing good then.
