Crystal XP2i

Pressure Gauge

The Crystal XP2i Digital Pressure Gauge measures pressure from vacuum up to 15,000 psi, depending on range, with accuracy as high as ±0.02% of full scale or ±0.1% of reading, model dependent. It features a 5.5‑digit display, selectable pressure units, and data logging capacity of up to 32,000 points. The gauge supports RS‑232 communication, operates from −10 °C to 50 °C, and is rated IP66/IP67 for use in industrial and hazardous locations.
