M2-870 - 3-1/8" (80 MM) LIQUID FILLED GAUGES


Sub Category:

These 3-1/8" (80 mm) American made liquid-filled gauges are simply the toughest in the industry and are backed by an extended warranty. Features an internal "breathing diaphragm" that eliminates air bubbles which can distort the reading. Thus, calibration is unnecessary. The seal on the internal diaphragm prevents freezing and corrosion. Gauges are sensitive instruments and should not be subjected to pressures beyond scale.
