*Typical Conditions are a temperature range of 54 to 90 degrees F, and a two year calibration interval.
**As Calibrated Accuracy is +/- (0.3% of reading + 0.05 Pa) under controlled conditions of 67 to 77 degrees F, four month calibration interval, and pressure readings averaged for 5 seconds. All gauges are verified to meet this specification at all calibration pressures.
***For use at temperature conditions outside the typical conditions in Note 1, or the as-calibrated range in Note 2, add an additional 0.037% of pressure reading per degree F over the stated range.
