with more easily read increments at low readings. The Model 25 is excellent for general
purpose work. The Model 40 inclined gage provides linear calibration and excellent
resolution throughout its range. The Model 40 ideally suite for air velocity and
air filter gage applications. Both gage types are capable of pressure measurements
above and below atmospheric as well as differential pressure measurements.
