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.
Check your owner s manual for compatibility, and if you re still not sure then give us a call and we d be happy to help you. To combat CO2 s drawbacks, players started using Compressed Air. It is also known as High Pressure Air (HPA), or Nitro, N2 or Nitrogen Tanks since they originally used pure nitrogen. HPA tanks are pressurized up to the tank s rating of 3000 psi or 4500 psi (Pounds per Square Inch). The pressure is then regulated through the tank s regulator down to 850psi (High Output) or 450psi (Low Output). HPA s #1 advantage is consistent pressure. The effects of firing fast or hot/ cold weather are negligible.
