Metal Digital Differential Pressure Gauges

We are offering digital differential pressure gauges.
The series a1 digital differential pressure gage is a patent pending microprocessor based digital pressure gauge for positive, negative, and differential measurement designed to be a direct replacement for mechanical gauges. The series a1 differential pressure gauges utilize an extremely stable piezoresistive sensing technology to give a standard full scale accuracy of 1%. For applications requiring better accuracy, the a1 is also available with 0.5% accuracy. The a1 pressure gauge also has an optional 4-20 ma output for applications requiring an output signal. The a1 features a bright ½" led display, which gives the gauge improved readability and precision. The a1 digital differential pressure gauges also feature 5 user selectable engineering units including in. W.c., mm w.c., cm w.c., kpa, and pa. The series a1 offers an improved look, and performance compare to mechanical gauges for a similar price
