Postby jn_andy » Fri Jan 24, 2020 1:34 pm

Digital pH Meter for lab How is the probe head? Is it a glass tube like the color left over? Or do you have a picture to show?

I have received the product already. Can it be used at all? - Turn on - Dip in water before wetting the head - and dip it in the substance you want to measure. No need to cal, right? Wait to use it for several months, then cal? How to wash, just release. running water You can keep it right? PS. The document is not clearly stated, so I would like to ask again to be sure.
