These low range instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instruments during calibration. With single digital push button, both ZERO AND SPAN are calibrated properly, nothing else is required. No additional reference pressure sources or separate calibration devices are necessary.SPECIFICATIONS Service Air and non-combustible, compatible gases.Wetted MaterialsConsult factory.Accuracy±0.25% FS for ±0.4˝ (100 Pa) and ±0.5˝ (125 Pa), ±0.5% FS for ±0.25˝ (60 Pa), and ±1% FS for ±0.1˝ (25 Pa).Stability±1% / year FSO.Temperature Limits0 to 140°F (-17.8 to 60°C).Pressure Limits1 psi max., operation; 10 psi burst.
