As with the original high accuracy BetaGauge PI 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.
