Models 7250xi and 7250i offer advanced percent of reading precision for increased capability with a single instrument, reducing the investment required to calibrate a wide variety of pressure devices and ranges.
The Model 7250xi provides 0.005 % of reading precision from 5 % to 100 % of the instrument’s range. This unmatched precision is achieved through unique quartz pressure sensing technology and multiple quartz sensors in a single instrument. Various ranges from 0 to 20 and 0 to 2 500 psi (0 to 140 kPa and 0 to 17.2 MPa) are available.
For pressure below the lower threshold of 5% for the 7250xi and 25 % for the 7250i, the precision becomes 0.005 % of the lower value. For example, a 1,000 psi (7 MPa) Model 7250xi provides 0.005 % of reading from 50 to 1,000 psi (0.035 to 7 MPa); the precision for pressures from 0 to 50 psi (0 to 0.035 MPa) is 0.005 % of 50 psi (0.035 MPa).
