3D Instruments 75514 Series Accu-Cal Plus Stainless Steel Case Battery Powered Digital Pressure Test Gauge with Stem Mount, 4-1/2" Dial, -5-30 psi Range, +/-0.05% Accuracy, 1/4" Male NPT Bottom Connection

3D Instruments Accu-Cal Plus digital test gauge from 3D Instruments incorporates the ultimate in pressure measurement technology to address the calibration requirements of current process monitoring and control instrumentation. The Accu-Cal Plus combines the accuracy of digital technology with the simplicity of an analog gauge and achieves performance, ease-of-use. Temperature compensation circuitry coupled with a rigorous multi-temperature calibration routine maintains this astounding accuracy over a temperature range of 32-122 degrees fahrenheit. A five (5) digit display with oversized 0.65-inches digits, high contrast, rotatable display and backlighting provides for superior resolution and excellent readability even at a distance or in poor light or at a bad viewing angle. As the perfect complement to the digital display. This safety oriented feature provides the user with a visual reference of their process pressure relative to the scale of the gauge. The Accu-Cal Plus digital gauge is housed in a polished 300 Series stainless steel case, which is rated waterproof according to NEMA-4/IP-65 specifications. All device controls including: POWER, ZERO, MIN/MAX and CONFIG are selectable via a robust Lexan keypad for reliable operation in adverse weather conditions. To reduce maintenance, low power circuitry provides for a 2000 hour battery life at a sample rate of 0.5/sec with no backlighting. This high-end pressure instrument provides for numerous user-configurable features such as: adjustable sample rates, damping (smoothing of displayed pressure values), Tare (re-zero across the span of the gauge), custom engineering units, MIN/MAX and "password protected" field calibration.
