The BetaGauge P. I. Digital Pressure Test Gauge takes the concept of an analog Test Gauge, and brings it to a new level, as only Beta Calibrators can do. The BetaGauge P. I. combines the accuracy of digital technology with the simplicity of an analog gauge, and achieves performance, ease-of-use, and a feature set unmatched in the pressure measurement world. Setup of the BetaGauge P. I. is fast and straightforward, through a menu-driven display, with minimal text, and intuitive functions, that is simple enough to allow the gauge to be used anywhere in the world, without the need for multilingual displays.
As with the original high accuracy BetaGauge PI gauges, the BetaGauge PIR 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 Reference Class BetaGauge PIR digital test gauges are available six ranges – 30 psi Compound, 30 psig, 100 psig, 500 psig, 1,000 psig, and 3,000 psig. Setup of the BetaGauge PIR is fast and straightforward, through a menu-driven display, with minimal text and intuitive functions, that is simple enough to allow the gauge to be used anywhere in the world without the need for multilingual displays. Pressure readings are displayed in any one of 18 standard engineering units, or in user-defined custom units, eliminating tedious conversion calculations. Readings are displayed on a 5-1/2 digit, 0.65″ high digital display and companion percent-of-range bar graph. Accuracy is temperature-compensated over a 0 to +50 °C range. The internal temperature sensor measurement can be displayed in degrees Celsius or Fahrenheit.
Crystal XP2i
The new and improved XP2i has all of the innovative features of the XP2 digital pressure gauge and more. Now Intrinsically Safe, Class I, Division I, Groups A, B, C, and D, temperature code T4 with a backlit display. Available with optional dual line pressure display to view peak and live pressure simultaneously – ideal for relief valve testing
