With 10 psi proof pressure on all ranges, they are available in five different air pressure ranges. Static accuracy is ±1% full scale in normal ambient temperature environments. The units are temperature compensated to less than ±0.033% FS/°F of thermal error over the temperature range of 0°F to +150°F. 1% accuracy, or better, improves variable air volume system performance.
