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.
Versatile Applications. Use the MAGNEHELIC gauges (range of 0.25-4.0 WC) to determine positive pressure differentials between the cleanroom and adjacent areas. MAGNEHELIC gauges can also be used to measure pressure drops across pre-filters and absolute filters.A PHOTOHELIC gauge/switch can also be used to control makeup or exhaust air dampers in order to maintain the room pressure within prescribed limits. All gauges can be mounted on a control panel.AGNEHELIC gauges can also be used to measure pressure drops across pre-filters and absolute filters.
