SECO Canal Measuring Stick and Accessoires
Canal depths and hidden points can be easy measured with a canal or base bar.
All canal benchmarks has two or three prisms mounted at a defined distance from each other in the vertical axis of the crossbar.
The top of the bar is set in a well-defined distance from the lower prism.
The bottom point results from the extension of the crossbar measurements..
A corresponding program must be installed on the total station.
For sporadic applications and/or low canal depths we recommend the very affordable SECO aluminum slat.
With the highest standards of accuracy you should use a VECTOR latte made from carbon fiber.
The specific advantages and disadvantages of the various.

| Material | Advantages | Disadvantages |
|---|---|---|
| Aluminium | - Attractive price | - High weight - Relatively high coefficient of expansion - Only for lengths up to max. 4 m suitable |
| GFK/CFK hybrid fabric | - Relatively inexpensive - Very robust - 20% lighter than aluminum |
- Less precision than CFK worse by straightness or concentricity of the tubes |
| Carbon fiber (CFK) | - 40% lighter than aluminum - Extremely rigid - Expansion coefficient 100-fold lower than for aluminum |
- High Price |
Ideal complement to the SECO channel bar for measuring the heights of branches, inlets, etc.. This bracket may also be used in conjunction with any SECO prism or antenna rod
