Ashcroft has engineered its Type 1082 and 1084 test gauges for sustained accuracy and high reliability. Available in 4 ½, 6, and 8 ½ in. diameters, the Type 1082 provides plus or minus 0.25%FS accuracy in ranges from vacuum through 10,000 psi. An external zero adjuster, temperature compensation, and Monel wetted parts ensure precision and media compatibility. For field calibration, the 3 in. Type 1084 pocket test gauge is the smallest portable master gauge available, covering ranges to 1000 psi with 0.5%FS accuracy.
