Spiegel Relaskop Alat ukur dimensi pohon

Alat ukur dimensi pohon Spiegel Relaskop An sophisticated, compact and robust but expensive instrument for measuring height, diameter, basal area and range. This tool is for pengkuran tree height measuring devices and some features capabilities: Rangefinder measures 33 ' , 66' , 99 ' or 132' baselines. Clinometer measures 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. FEATURE: Slope Correction Device gives topographic correction when using two chain tape with trailer. Used by foresters since 1954, six instruments Relaskop merge into one. Save time and money when the timber, variable plotting or Three P sampling. Each unit weighs only 14 oz.; Furnishing complete with leather case 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. SPECIFICATION: 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 tree site) to the location of the point 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 are anticipated. 2. Sight at the required point, while holding down a break to allow the scale to rotate freely. 3. Read from the scale of the diameter after the scale has been settled a large number of bands ( with the number 1 printed on them) ( L) ; small number band ( 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 to the band) , 0.4 ( nearly half) , 0.6 ( just over half) , 0.8 ( amost full narrow band) . 4. Diameter was 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.
