Proto Screw Shield for Arduino (Assembled) _RPI_USB_KEYB Dimensions (assembled): 69mm x 53mm

Dimensions (assembled): 69mm x 53mm x 2mm

The microtip allows for finer control but is a little harder to use (because it doesn't deposit as much silver at once)

you'll be able to play immediately after simple assembling and programming

ORP follows a linear relationship and does not need instrument adjustment as much as it needs electrode maintenance

Proto Screw Shield for Arduino (Assembled) _RPI_USB_KEYB Dimensions (assembled): 69mm x 53mmCombines the power of screw shield and prototyping shield.
