I'm looking for information on hand held psychormeters/hygrometers and am wondering if anyone has had good experiences with particular brands/models. I'm looking for accuracy around +/-.5% RH for lab humidity transmitter validation.
Any recommendations?

I don't need high levels of accuracy as this not a critical process control HVAC application.

Just like any other humidity sensor, get them calibrated at no more than one-year intervals.
Good on ya,

Most room sensors are good for +/-5% and some better ones do +/-3%, so a +/-1% calibration checker will be fine for your purposes. If you have higher precision sensors, then you need to remove them and calibrate them over a salt bath.
The real value in the handheld is that it can be readily calibrated, which is where you get your confidence in measurement.
