Description

Laboratory installation — desktop version: pressure gauges, pressure sensors and controls are installed on the panel, at the base there is a receiver and a compressor with a power supply.
Allows you to study means and methods of measuring pressure; gain skills in measuring pressure using dial gauges and pressure sensors of various types; evaluate the error of measurement results.
The installation includes a set of pressure sensors, dial gauges, a receiver, a power source for pressure sensors, a compressor for creating pressure, and a multimeter.
