I was watching a UTube video and saw a box with a male 510 connector on one end that screws into your PV and a female 510 connector on the other side of the box that you screw your atomizer into and a volt meter in the middle. It was used to check what the voltage was while the unit was in operation.
Is this something you can buy "premade" or do you just have to purchase the connectors and volt meter and build your own?
