Ametek Crystal XP2i [1BARXP2I-S2] Digital Pressure Gauge, 0.02% FS Accuracy, 1/4NPT Male, Bottom, 1 Bar Gauge.

The Crystal XP2i Series are unlike any other pressure gauges. Their looks, performance, and construction are different from anything else available. Pressure gauges from the XP2i Series are very rugged. Their 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 case is gasketed and water resistant per NEMA4 and IP66. A replaceable filter in the sensor keeps out debris.Unlike mechanical gauges, Crystal XP2i Series pressure gauges have the ability to survive large over-pressure events with no change in calibration.The XP2i Series is very easy to use. No menus - just buttons. 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 with a pressure controller, and you can calibrate XP2i's automatically.
