| Calibration |
Meets ASTM Standard E779-03, E1554-07, CGSB-149.10-M86, EN 13829, ATTMA Technical Standard 1 and NFPA 2001, RESNET and US ACE |
| Recommended calibration interval |
Two years |
1Typical Conditions are a temperature range of 54 to 90 degrees F, and a two year calibration interval
2As Calibrated Accuracy is +/- (0.4% of reading + 0.045 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.
3For 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. |
