Spiegel Relaskop
An sophisticated, compact and robust but expensive instrument for measuring height, diameter, basal area and range.
This tool for tree height and pengkuran gauge the ability of some features: Rangefinder size 33 ' , 66' , 99 ' or 132' baselines.
Clinometer size of plus or minus the vertical angle readings in degrees or percentages.
Dendrometer diameter outside bark of trees, each altitude.
Angle Gauge provides a direct measure of basal area per hectare.
Spiegel Relaskop FEATURE:
Device Correction of topographic slope gives a correction when using two chain tape with a trailer.
Used by foresters since 1954, six Relaskop merge into a single instrument. Save time and money when its 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 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 the point directly below the desired site tree) to the location of points where necessary ( eg change in diameter) can be viewed. 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 the button recess to allow the scale to rotate freely.
3. Read the scale of the diameter after the scale has settled a large number of bands ( with the number 1 printed on them) ( L) ; a small number of bands ( 4 narrow band just to the right of a band) ( S) ; and fractional estimates of 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 make sure the diameter appears correct. 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.
