Spiegel Relaskop: tree-dimensional measuring tool
Spiegel Relaskop: tree-dimensional measuring tool
An sophisticated, compact and robust but expensive instrument for measuring height, diameter, basal area and range.
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
1. 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.
2. Sight at the required point, while holding down a break to allow the scale to rotate freely.
3. 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) .
4. Diameter is calculated as ( cm) = H * ( L + 0: 25 * ( S + s) ) * 2
5. 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.
