Six models are offered for either two or four-channel testing at high (0-10 psig), low (0-1 psig) or standard (0-3 psig) pressure. All models feature a transducer repeatability of 0.05% F.S.D., a transducer sensitivity of < 10-5 psi (STD), 0.01 second timer increments and a low internal volume (<1.5 cm3 ). Up to 1000 test records can be stored and analyzed for mean standard deviation or mean +/- 3 standard deviation. An easy-to-use touch panel displays all phases of test status, including reasons for rejects. The M1075-94X can either be used as a stand alone instrument or integrated with a PLC or PC.
