Micromanometer ΜV-250-0,02

Sell ΜV-250 manometer liquid compensation with micrometer screw.

ΜV-250 — micromanometer liquid compensation with micrometer screw. Designed to measure pressure, vacuum and differential pressure of non aggressive gases in the range 0...2500Па.
The device has an accuracy class of 0.02.
Can also be used as a standard instrument for calibration of Magomedov, differential pressure gauges etc. of the devices with the lower class. t
The operation of the instrument based on the principle of communicating vessels, where the measured pressure or vacuum is determined by a balancing column of liquid is distilled water.

Micromanometer compensation ICWC-250 suitable for measuring overpressure, underpressure or differential pressure of air and non-corrosive gases range from 0 to 2500 PA (0 to 250 kgf/m2). In addition to its primary purpose micromanometer can be used as a model for testing of Magomedov, differential pressure gauges and other devices of lower accuracy classes.
Micromanometer can be used in the laboratories of the metrological centers, promyshlennyh companies and repair shops. Is used as an exemplary device for checking naphrameru, tahomaru, tranporation, pressure gauges, pressure-vacuum gage, vacuum gauges with low accuracy class
Principle of operation: in communicating vessels, in which pressure or vacuum is measured by a column of water distilliation
