Martel BetaGauge PIR-PRO Rear Mount Digital Pressure Calibration Test Gauge, 0 to 30 psi

As with the original high accuracy BetaGauge P.I. PRO gauges, the BetaGauge PIR PRO takes the concept of a simple analog Test Gauge and combines it with the accuracy of digital technology. The new Reference Class gauges provide exceptional performance with ±0.04% of reading accuracy, especially when operated below 50% of their range. The BetaGauge PIR PRO builds on the proven performance of the BetaGauge PIR with a new purpose designed Zinc-Aluminum Alloy High Pressure Cast housing. The new housing improves the environmental integrity of the gauge in a lighter and smaller yet more rugged form factor
