PIPE-MIC II  Measure pipe inverts and sizes fast, easy & accurate.

​Made in the USA​* Measurements are more accurate because you are measuring with a vertical plumb rod.

To use:
* You can direct read the depth of the invert when the pin is set at "zero offset" on the PIPE-MIC   II .
* If you need clearance under rod to measure an invert move the pin to "1' vertical ​​offset hole"
* If you need clearance under rod and a pipe that is hard to reach you can add a 1 ft. extension.
   (1 ft. extension sold separately) Move pin to " 1 ' vertical offset w/ 1' extension" hole.
To size a pipe:
The foot is 0.33 or 4". Take the reading from the rim, pull up and take reading plus 0.33 and that is your pipe size.​​​​
