    • Great meter
Size: 1/4" NPT (MF5706)
This is a great flow meter to measure compressed air, nitrogen, oxygen, or any other gases. This meter is easy to install and monitor for leaks or system maintenance. Very accurate as this is lab graded. LCD is large and easy to see, and the display rotates for easy viewing from different angels. Price is reasonable for a good flow meter, so great deal. Very happy with this meter. ... show more
