Overview

The conventional 2-1/4" Manifold gauge is lightweight with a slim design and uses a single diaphragm. The newer 3-1/8" and 2-1/4" gauges incorporate a dual diaphragm design which improves the longevity and reliability of the instrument. Standard markings are black and white.

Reviews

Easy to install and works great. The instructions are a little hard to follow. Suffice it to say that this unit assumes the ambient temperature is 75 degrees and will display a cht that starts there. So, if the ambient temp is less than 75 degrees the unit is assuming its hotter than it really is. So, you subtract one degree for each degree below 75. If its hotter than 75, the unit assumes its cooler than reality, so you add one degree for each ambient degree above 75.
