Pressure and Vacuum
From the invention of the syringe pressure pump in 1594, the manometer in 1644,
and the breakthroughs in 1648, 1661, and 1820 with Pascal’s, Boyle’s and Lord Kelvin’s
laws of physics, the Bourdon tube pressure gauge was invented in 1843. Advances
during the 1900’s in physics and technology saw the development of the strain gauge,
transducer, and silicone diaphragm for measuring pressure. Today’s instruments are
capable of measuring pressures from near perfect absolute to ranges and uncertainties
unthinkable of in the days of Pascal, Boyle, and Lord Kelvin. InnoCal’s highly trained
technicians still use these laws to ensure that quality measurements are made.
InnoCal performs accredited NIST-traceable pressure and vacuum calibrations on
absolute-, atmospheric-, and gauge-pressure vacuum or pressure gauges, transducers,
and barometers. Our skilled technicians use NIST-traceable standards in a controlled
environment. InnoCal’s calibration reports include measured data and corrections
(if required) to meet the most stringent quality and scientific requirements.
- Testing range from 30 in. Hg, to 10,000 psi at uncertainties as low as
0 to 5000 psi: (K=2) ±0.005 psi + 0.00019/psi
- Vacuum from 0 to 30 in. Hg: (K=2) ±0.04 in. Hg
- Barometric pressure from 600 to 1060 mBar: (K=2) ±0.51 mBar
Note: InnoCal can provide accredited pressure calibrations up to 5000 psi.
