20px; text-align: justify;">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 &frac12;&quot; 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</span><br style="font-family: verdana;
