I need mainly a portable outside device. I work out in the sun and want it for temp and humidity readings. will this work for my needs. Thanks

I wouldn't leave it outdoors. It is mainly a portable, instant read device.

Can it be used to check humidity of bark chips and sphagnum moss around potted orchid?

Yes it probably could, This tool is very sensitive as I do a lot of work in HVAC on rental properties that I own. Living in hot humid florida it will flat out pick the slightest leaks of outside air around door gaps, window frames, sliding glass doors plus what you have coming out of you AC ducts. I found it to be very usefull. Be carefull when handling the probe tip. I;ve it for a year now and after heavy use probably I should check the calibration which the instructions tell you. Also measures wet and dry bulb temperatures. Good luck with your Orchids
