PIR PRO Reference Class Digital Pressure Gauge offers the highest accuracy in its class

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
