We are offering hyere the Analog Pressure Gauge that have a needle that directly responds to changes by pointing to numbers on a scale corresponding to the pressure sensed by the measuring element. Movement of the needle translates to variations in temperature or flow, which are easily noticed and monitored. It is an instrument that can measure and display the value of a physical characteristic. It is an instrument for measuring the condition of a fluid (liquid or gas) that is specified by the force that the fluid would exert. The offered Analog Pressure Gauge is very accurate and easy to use.
