Preiswerte Differenzdruckmessgeräte

Sensocon offers three different low cost differential pressure gauges. The S2000 and P2000 are both mechanical, diaphragm operated pressure gauges. The difference between the two gauges in the housing material, the S2000 has an aluminum housing and the P2000 has a lower cost ABS housing. The A1 is a Digitales Differenzdruckmessgerät and a step up from the mechanical products. While the A1 fits the same size hole as the S2000 and P2000, the most notable difference is the A1 requires power (16-265 VAC/VDC).
