Description
The 321A-15CV-30A is the standard version, with sensor 1 at 15 psi compound (15CV) and sensor 2 at 30 psi absolute (30A). In the code, G means gauge, A absolute and C or CV compound (vacuum and pressure). The Martel BetaGauge 321A is a handheld pressure calibrator with two isolated internal pressure sensors, so one instrument can read two ranges, such as a low differential range and a high static range. It also accepts a Pt100 RTD for temperature and measures mA signals, which makes it well suited to gas flow computer verification. A backlit graphic display shows up to three readings at once. Gas measurement technicians and instrument shops use it for custody transfer checks and general pressure calibration.
