The Crystal XP2i is an intrinsically safe digital test gauge certified for Zone 0 (gas) hazardous areas.
It offers pressure ranges from vacuum to 1,000 bar with up to 0.02% accuracy and 0.0001 bar resolution.
Optional data logging records 32,000 points at up to 4 samples per second.
Every XP2i includes an ISO/IEC 17025 accredited (NATA equivalent) calibration report with data at 5 points across the -10 to +50°C temperature compensated range.

Certification and Standards Compliance

XP2i gauges are certified as intrinsically safe to IECEx, ATEX and CSA equipment schemes.
They are compliant with CE Electromagnetic Compatibility and Pressure Equipment Directives, and Australia Radiocommunications (Electromagnetic Compatibility) Standard 2008.
The XP2i is also approved as a portable marine test instrument in compliance with Det Noriske Veritas Rules for Classification of Ships, High Speed & Light Craft and Offshore Standards.

Measurement Range and Accuracy

The XP2i measures from vacuum to 15,000psi / 1,000 bar with 0.02% laboratory reference grade accuracy and precise 0.001psi / 0.0001 bar resolution.

Calibration Interval

The XP2i's recommended calibration interval is one year, although exceptional long-term stability means lab tolerance adjustments are often not required.
Automatic calibration reminders and alerts ensure safety and compliance, and an XP2i can be locked if the recalibration date has passed.

Thread Types and Connections

An internal 7/16"-20 medium pressure female thread adapts to a wide number of device and process connections using fittings and hoses from Crystal’s CPF range.
An interchangeable 1/4” NPT, G1/4” BSP or M20 x 1.5mm adapter is included as standard and helps to protect the XP2i’s connection port from everyday wear and tear.

Suitable Industries and Environments

XP2i gauges are trusted worldwide by any business or industry with a need for reliable, high-accuracy pressure testing and calibration.
Intrinsically safe and globally certified for use in Zone 0 hazardous areas, the rock-solid XP2i operates dependably in the most extreme working environments on earth.

XP2i FAQs

What industries commonly use the Crystal XP2i?

The XP2i is found throughout all industries including energy, resources, oil, gas, chemicals, processing, manufacturing, civil and engineering.
XP2i gauges are regularly used in hydrostatic pressure testing, pressure safety valve testing, wellhead monitoring, sensitive equipment calibrations and long-term data recording applications.
The XP2i is also regularly employed as a high precision reference standard in accredited calibration laboratories around the world.

Is the XP2i IECEx certified for hazardous areas?

Yes. The XP2i is IECEx certified as intrinsically for use in Zone 0 hazardous areas where flammable gases or vapours are likely to exist under normal operating conditions.
This makes it suitable for many high-risk environments with potentially explosive atmospheres such as off-shore platforms, oil refineries, petrochemical plants and gas processing facilities.

Is the XP2i certified to other hazardous area standards?

Yes. Every XP2i gauge is Ex-certified as intrinsically safe and non-incendive for use in Zone 0 (gas) and Class I, Division 1 hazardous areas according to the following equipment schemes and systems.

IECEx (Global)

• Ex ia IIC T4/T3 Ga
• Certificate FTZU 12.0009X

ATEX (Europe)

• II 1G Ex ia IIC T4/T3 Ga
• Certificate FTZU 12 ATEX 0048X

CSA (North America)

• Class I, Division 1, Groups A, B, C and D T4/T3C
• Certificate 1450352 (LR 110579)

Is the Crystal XP2i calibrated to Australian NATA standards?

Yes, and then some. Every XP2i gauge is supplied with a NATA equivalent, A2LA endorsed, ISO/IEC 17025 accredited calibration report to ensure compliance for regulated industrial use across Australia.
NATA and A2LA are both signatories to the ILAC mutual recognition arrangement (MRA), which is a global agreement that recognises these organisations as equivalent and accredited to the same international standards.
The XP2i’s initial calibration certificate also includes data at five temperature points between -10 and +50°C, improving on the single ambient temperature data provided with standard NATA certification.

Can the XP2i be used for testing and calibration in hazardous areas?

Yes. Intrinsic safety, accuracy to 0.02% and resolution to 0.0001 bar make the XP2i the perfect go-anywhere pressure test and calibration tool for devices in hazardous areas, out in the field, on the bench or in the lab.

Is the XP2i suitable for oil and gas applications?

Yes. With Ex ia / Zone 0 (gas) intrinsic safety, the XP2i is designed, manufactured and certified for any oil and gas pressure testing or calibration application.
Also carrying an IP67 protection rating, the rugged XP2i is dust-proof and immersion-proof, and performs comfortably in the harshest environments and workplaces.

What is the accuracy / uncertainty rating of the XP2i?

Standard accuracy is 0.1% of reading.
Full scale accuracies of 0.05% and 0.02% are also available.
Maintaining accuracy across wide pressure and temperature ranges, one XP2i can replace multiple conventional gauges - saving on equipment, maintenance and calibration costs while streamlining efficiency and lightening your tool bag!

Can the XP2i be used for data logging?

Yes. DataLoggerXP firmware upgrade can be added to any new or existing XP2i gauge, providing internal recording for 32,000 data points and adjustable sample frequencies from 4 times per second to once every 18 hours.
DataLoggerXP will record averages, peaks, or simply the pressure reading; perfect for high-accuracy pressure to vacuum transitions, process or environmental monitoring, leak detection or sterilization processes.

Can the XP2i be used for leak testing?

Yes. With a dual-line display the XP2i can simultaneously show live pressure plus leak rate, tare or peak values.
It will also show differential pressure when connected to a second unit.
