The manometers, vacuum meters and compound pressure gages showing for precise measurements of MPTI, VPTI, MVPTI are intended for measurement of excessive and vacuum gage pressure of nonaggressive, uncrystallizable liquids, gas and steam, including oxygen and application in spheres of the state metrological control and supervision (GMKIN) and the state system of industrial devices and an automation equipment (GSP). Devices of accuracy rating 0,4 are issued with the zero adjuster only on the body.
Devices of accuracy rating 0,4 it is allowed to use as reference measuring instruments at observance of necessary ratios of limits of the allowed main errors with working measuring instruments. The technique of checking 5ShO.283.421 is approved by GTsI SI Federal State Unitary Enterprise VNIIMS.
