Options + NIST Calibration Certificate Order Code: /C - NIST (National Institute of Standards and Technology) Certification of Calibration states that the pressure gauge was tested at multiple test points and is within its stated tolerance of accuracy. Gauge is shipped with a sticker on the side of the gauge noting the certification number and date, and NIST certificate. Dual Scale Dials US Gauge offers most pressure ranges in dual scale, such as psi & kPa, psi & BAR, psi & kg/cm2, or single scale metric such as kPa, kg/cm2, or BAR.
These Bourdon vacuum pressure measurement gauges are low cost being quick and easy to use. However, they are very low accuracy gauges. Each tick mark in the vacuum is around 100 Torr. These Bourdon vacuum pressure measurement dial gauges are 3 inches high and have 1/4 inch NPT Male. They are made of corrosive resistant stainless steel.
