Crystal Engineering XP2i is an ultra rugged, intrinsically safe, digital test gauge with 0.1% of reading, 0.02% of full scale, or 0.05% of full scale accuracy levels.


0 to 20% of Range:

± (0.02% of Full Scale)

Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.

20% to 110% of Range:

± (0.1% of Reading)

All models indicate vacuum, but vacuum specification applies to 15 psi, 30 psi, 100psi, and 300psi models only.


± (0.25% of Full Scale*)

Not recommended for continuous use below -14.5 psi.


* Full Scale = -14.5 psig

Refer to XP2i-DP data sheet for gauges that are intended for continuous high vacuum use.


Vacuum to Full Scale

S2 Option:± (0.02% of Full Scale) 15 to 25° C
± (0.05% of Full Scale) -10 to 15° C,
25 to 50° C, typical
S5 Option:± (0.05% of Full Scale) -10 to 50° C



Temperature Range:

-10 to 50°C (14 to 122°F)

Non-condensing. No change in accuracy over operating temperature range. Gauge must be zeroed to achieve rated specification.




5.5 digits

LCD readable in sunlight with bright backlight.

Single Line Display:

16.9 mm (0.67") high

PSV mode is intended for Pressure Safety Valve testing, and requires software to enable.

Dual Line Display:

Main Display: 13.9 mm (0.55")
Secondary Display: 5.3 mm (0.21")

Display Rate:

4 readings/second (standard)
8 readings/second (PSV mode)
