 Intro ClinoMaster Clinometers/Heightmeters |
 |
This type of hand held clinometer/heightmeter is perfect for quickly and very accurately measuring vertical angles/heights.
Typical users of this kind of instrument are: Forestors, geologists, engineers (construction, telecom), miners, architects and others who have to measure vertical angles/heights in for ex. the forest, city, quarries, mines, caves, buildings etc.
The benefits of the precision clinometers/heightmeters are:
 Very easy to read thanks to the light strong, crystal-clear scale
Available with different angle/heightscales depending on user category
Available with a distance prism making it easy to measure the horizontal distance to the object of whichs height is to be measured
Available in a special Forest-version with a built-in relascope for timber volume calculation
Quick settling-time thanks to the liquid-damped scale
Extremely accurate

| Determination of the distance |
|
Let us say that you are to use the 15 metre height-scale in your CM 1015/2025 LA/DP for measuring the height of a tree. Unfold 2 sections of the Lath (making a total of 3 sections visible).
1. Hang the Lath on the tree and move back a few metres.
2. Hold the ClinoMaster in your right hand and sight through the Distance Prism (situated in the corner of the aluminium body).
3. You will now see two Laths through the Distance Prism - this is an optical illusion created by the Distance Prism.
4. Adjust your distance to the tree until the two Laths seem to be edge to edge above each other. You are now at the correct distance i.e. 15 metres. (If the image of the Lath seems to be split, you are too close. If they have came apart you are too far away).
5. Sight towards the top of the tree through the ClinoMaster's sight and read the height at the 15 metre scale. Remember to add the height of the tree below the 0 meter marking in the instrument.

|
360% 0-90° scale and 0-150% scale.
400% 0-100 gon scale and 0-150% scale.
SEC/% Secant scale which enables measurement of sloping distance when horizontal distance is known and vice versa and 0-150% scale. 1015/2025 Height scales for distances 10, 15, 20 and 25 metres to the object. By doubling or halfing the height reading, it can easily be used at 5, 10, 15, 20, 25, 30, 40 and 50 metres distance from the object.
2015% Height scales for distances 15 and 20 metres to the object. By doubling or halfing the height reading, it can easily be used at 10, 15, 20, 30 and 40 metres distance from the object. Also equipped with a 0-150% scale.
2015 DEG Height scales for distances 15 and 20 metres to the object. By doubling or halfing the height reading, it can easily be used at 10, 15, 20, 30 and 40 metres distance from the object. Also equipped with a 0-90° scale.
66% Height scale for distance 66 feet to the object which is to be measured and a 0-150% scale.
