BetaGauge PIR PRO Reference Pressure Gauge

The BetaGauge PIR PRO Reference Pressure Gauge provides exceptional performance with ± 0.04% of reading accuracy, especially when operated below 50% of its range.
The BetaGauge PIR PRO reference pressure gauge is available in pressure ranges up to 10,000 psig.
Additionally, a compound ranges is also available.
Readings may be displayed in any one of 18 standard engineering units or in 1 custom user-defined unit to eliminate tedious conversion calculations.
Rugged zinc-aluminum alloy high pressure cast housing provides environmental integrity of the gauge in a small, light package.

The PIR Pro includes a 5-1/2 digit digital display. The 0.65" numerals and companion bar graph provide
an easy to read display, even from a distance. A number of features provide additional ease of use.
The reading sample rate can be user adjusted to match the type of measurement required.
Other features include MIN/MAX function, Auto Power Off and backlight control.
In addition to a ZERO function that compensates for sensor drift, large residual system pressures
can be nulled using the TARE adjustment.
