American Sensor Technologies” AccuGauge 17-4 PH stainless steel digital pressure gauge is free of welds, internal o-rings, and fluid-filled cavities, making it a good fit for applications that require high proof and burst pressures. Built for robust use, the transducer is packaged in a rugged NEMA 4, IP65 polycarbonate body. In addition, the gauge uses AST’s patented Krystal Bond technology to provide long-term stability, high output, and no zero shifts. The gauge can measure pressure in PSI, Bar, kg/cm2, inches Hg, inches H2O, and ATM, making it a good fit for all pressure measurement types. The gauge is also vacuum-calibrated for pressure ranges under 500 PSI. A Min/Max feature allows the user to track minimum and maximum pressure readings on the digital gauge with a push of a button. A large four-digit LCD display accurately displays measurement, eliminating the guesswork related to analog dial gauges. A backlit display provides improved visibility in dark and marginally lit areas. Units operate from a 9V long-life alkaline battery that offers a typical life of 4,000 operating hours. A four-bar battery indicator on the unit display indicates a “LOW BAT” warning before the battery is fully discharged. The gauge also has an automatic power-off feature to offer continuous use of the gauge before changing the battery. As an added safety feature, the display on the gauge will flash when the pressure reaches 110 percent of the rated pressure. The gauge offers pressure measurement accuracy of < +/- 0.5 percent of full scale, BFSL (including nonlinearity, hysteresis, and nonrepeatability) over operating temperature ranges of -10 C to 70 C (-10 F to 160 F).
