Invert measurement rod

The Vertical Rod

MEASURE INVERTS WITH EASE

Our calibrated vertical rod allows you to quickly measure recessed structures at a variety of angles ranging from 0-30 degrees, simply extend the rod, level and read.

Never remeasure another invert!

Four calibrated sides allow you to measure from multiple angles and achieve a redundancy of measurement. Get the right invert the first time every time.
Speed through measurments

The Vert rod allows you to quickly collect invert data at multiple angles without second guessing your measurements. Save time and eliminate multiple site visits.
Heavy duty tooling

High strength, aircraft grade aluminum ensure durability and easily allows the rod to push through silt and debris.
Office Check

Use multiple angles to achieve a redundancy of measurement or have your crew match the digital level on the zero side to the angle of the calibrated side they decide to use. The slope distance times the cosine of the angle will give you the corrected vertical distance.

inverts should be Accurate and easy

With over 30 years experience in field survey we at Accurate Inverts knew there had to be better way. Measuring tapes, clip on attachments and complicated devices do little to reduce the time it takes to measure an invert and worse yet, they don't improve the accuracy. This common problem often leads to unreliable information, forcing you to go back and remeasure, wasting time and money. We fixed that problem, now simply extend the Vert Rod, level and collect your measurement.

FAQ

How does it work?

Each side is calibrated to the cosine of the assigned angle giving you the corrected vertical distance when level.

What if i can't measure at the angles provided?

A digital angle finder is included on the zero side of each rod. This allows you to find specific angles and calculate the corrected vertical distance. Instructions included.
