PG5 digital pressure gauge by Automation Products Group, Logan UT, has a 5-digit display with 0.4-in characters. The self-powered (9-V battery) uses MEMS-based sensing and is available with ranges from vacuum to 500 psi, and from 0 to 10,000 psi, at ±0.25% accuracy of full scale. The unit’s all-stainless-steel sensor resists most vibration and shock. The gauge provides highly accurate readings even with pulsating pressures. User-selectable functions include auto-off (2, 4, 8, 16, or 32 min.), maximum and minimum readings, and units of measure.
