The caliper is an important tool for providing an exact measurement. Knowing the thickness of an MEA or gasket component will ensure that the assembled fuel cell provides the right compression to the MEA.
A dial lets you check your measurements at a glance. Calipers take inside,outside,depth, and step measurements, unless otherwise stated. All with built-in backlash control to prevent the needle from deviating (unlessnoted). Made of stainless steel and include a case.
