• Measure pipe inverts and sizes fast, easy & accurate with the Pipe Mic
• Measurements are more accurate because you are measuring with a vertical plumb rod.
• Made for SECO 25' SVR Level Rods, and USL Level Rods
• Made of lightweight (two pounds) non rusting aircraft aluminum.
• No tools needed to attach to rod.
• Slides on and off in seconds.
• Round foot design slices through material at bottom of pipe (like a pizza cutter) and insures accurate invert and pipe diameter measurement.
• By pulling a pin in just seconds you can go from zero to 1 ft. vertical offset for clearance under rod.
• Pronounced "PIPE MIKE 2"
• Made in the USA

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 a rod and a pipe that is hard to reach you can use the 3ft. arm instead (purchased separately).*
• Move pin to "1' vertical offset w/ 3' Arm" 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.

Option Details:

• 1702PM2: Pipe-Mic II
• 1736ARM: 3 ft. Arm with Wheel 
• (The 1ft extension (1712EXT) is no longer available)

Examples for sizing Pipe:

• 4" Pipe Size = 0.00 movement
• 6" Pipe = 0.17
• 8" Pipe = 0.33
• 10" Pipe = 0.50
• 12" Pipe = 0.67

(Remember you Pipe-Mic II wheel diameter is 0.33 or 4")

Optional 3 Foot Arm

• Part number 1736ARM
• 3' with 4"diameter foot.
