342.11 test gauge with WIKA transport case

Description

342.11 The test manometer with WIKA transport case and acceptance test certificate is a precision gauge used for the calibration of pressure gauges. The accuracy of the test gauge means that the error in the reading shall not exceed 0.25 % at any point on the scale in either rising or falling pressure.
