Ametek Crystal XP2i-DP Series Pressure Gauge is an ultra rugged, intrinsically safe, differential pressure gauge with 0.1% of reading accuracy, capable of continuous vacuum measurement. The displays are protected by a hard polycarbonate lens, and their circuitry is mounted in elastomer for shock resistance. The case and sensor are made of stainless steel to provide resistance to corrosion as well as an excellent barrier to emissions from cell phones, two-way radios, and other electrically noisy equipment.

The XP2i-DP Series is very easy to use. They can be calibrated via the keypad or the RS232 port. The display backlight is one of the best available on this type of pressure gauge. Combine an XP2i-DP with a pressure controller, and you can calibrate XP2i's automatically.
