East Hills Instruments

Specifications include all effects of linearity, hysteresis, repeatability, temperature, and stability for one year. Differential Pressure Accuracy 20% to 100% of Full Scale ±(0.1% of Reading) 0% to 20% of Full Scale ±(0.02% of Full Scale) Static line pressure effect is 0.0003 psi per lowest applied test pressure and can be eliminated by zeroing the gauge while the lowest test pressure is applied to left (+) and right (-) ports simultaneously. Pressure Ranges (see table below for details) Note: Density of water conversion can be selected via the keypad: 4°C, 60°F or 20°C /68°F.
