That item is assembled to make it convenient in an outdoor setting,
with a long wire and robust package -
but its just a standard 'Ag/AgCl reference electrode' aka "Silver Chloride Reference Electrode"

Any chemical testing laboratory uses them - water, health, industrial
if you google, you can find them for sale from many sources

And Its simple to make - you can find instructions & youtube video
