Hi, does this come with a calibration certificate??

Don’t think so dose what I want it to do

do you have to add water to the instrument for wet bulb temperature

No, just load 9V battery, then turn on device, it will display readings. This device can only be used to measure temp and humidity of air.

Does it work well outdoors or is for indorrs use only?

Yes this will take outdoor environmental air conditions however external environmental conditions are better read with a corresponding air flow rate using an anemometer as wind chill will effect your results.

Hi can you tell me what size thread is on the back of the device so I can fit on a tripod ?

Diameter of installation hole: 5mm
