    • Liquid Filling
      • Order Code: LG, LS, or LM - Extend the life of your pressure gauges. Liquid filled pressure gauges are generally recommended over dry gauges due to performance and durability. When USG’s liquid filled gauges are filled with Glycerin (LG), Silicone (LS), or Mineral Oil (LM) you’re helping to prevent gauge failure commonly caused by excessive vibration or pulsation. Glycerin is the most common fill fluid and is typically used for room-temperature applications. Silicone is used for more extreme temperature applications. Mineral Oil can also be used for higher temperature ranges.
    • 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. Dual scale dials are available at no extra charge. Please reference our data sheet or email customer service at with any questions.
