The Model 1403 and 1404 Test Gauges are stem or low mount pressure gauges for testing and validation, with an ASME B40.100 Grade 3A accuracy (±0.25%). The Model 1403 and 1404 has a chemical resistant aluminum solid front case with a blow out back design. This pressure gauge has a mirrored dial and knife-edged micro-adjustable pointer to reduce parallax readings. The 1403 and 1404 is available in 4.5” and 6” gauge sizes; the larger size provides better dial readability.

The gauge has a low mount brass socket available in both a .25” or .5” NPT connection, with a seamless phosphor bronze or beryllium cooper bourdon tube. Pressure ranges are from Vacuum to 5000 psi. The Model 1403 and 1404 has a geared ARC-LOC movement to minimize friction and wear. These gauges are available with a NIST Calibration Certificate option.
