Tree dimensional measuring tool

This tool is for pengkuran tree height and gauge the ability of some of the features: Rangefinder size 33 ' , 66' , 99 ' or 132' baselines.

Clinometer size plus or minus the vertical angle readings in degrees or percentages.
Dendrometer diameter size of trees outside the skin, every height.
Angle Gauge provides a direct measure of basal area per hectare.

Spiegel Relaskop FEATURE:

Slope Correction Device topography gives a correction when using two chain tape with a trailer.

Used by foresters since 1954, six instruments Relaskop merge into one. Save time and money when the timber, or the Three P variable sampling plan. Each unit weighs only 14 oz.; Furniture complete with leather bag and instructions.

American Scale reads in English units ( sq. ft / acre, inches, feet) for BAF 5, 10, 20 and 40. Also includes a 66 ' slope correction scale. Ideal for use on trees smaller than 96 " dbh.

General instructions for use to measure the diameter Relaskop

Measure the desired horizontal distance ( H m) from the base of the tree ( or point just below the desired site tree) to a point location where necessary ( eg change in diameter) can be seen. Please note that you must be at least 5 m away for every 20 cm in diameter anticipated.

Sight at the required point, while holding down a break to allow the scale to rotate freely.

Read from the diameter scale after the scale has settled a large number of bands ( with the number 1 printed on them) ( L) ; small number of bands ( 4 narrow band just to the right of a band) ( S) and the estimated fractional each small group ( s ) . Estimate the fraction of small bands such as 0, 2 ( only the band) , 0, 4 ( almost half) , 0, 6 ( just over half) , 0.8 ( amost full narrow band) .

Diameter is calculated as ( cm) = H * ( L + 0: 25 * ( S + s) ) * 2

Check to ensure the correct diameter appear. Note that L will be 0 or 1, S will be 0, 1, 2, 3, 4 and s will be a fraction less than 1.0.
