Kits

TK00 Axis Extension Kit
consisting of an axis extension and a flange type 1. Typically used to have a second flange for additional instruments on the secondary axis.
TK01-ex1 Shading Disk Kit (Single)
includes all parts that are needed (in addition to the base unit) to operate a single shaded pyrano- or pyrgeometer with INTRA. The parts included are the followings: 2 axis extensions, 2 flanges type 1, 1 pyranometer-flange (for instrument with or without ventilator), 1 Shading disk mechanism, 1 arm extension of length 160, 210 or 510 mm and a shading disk of diameter 63 or 90 mm. Please specify extension of the parts number: -ex1 = -nnn-ii-dd, where nnn is for the arm-length 065, 070 or 1000 and ii is for the instrument plate KZ, EO,EK, KZV or EPV and dd = 63 or 90 is for the diameter of the shading disk.
TK02-ex2 Dual Shading Disk Kit
includes all parts that are needed (in addition to the base unit) to operate two shaded pyrano- or pyrgeometers with INTRA. The parts included are the followings: 1 axis extension, 1 flange type 1, 1 instrument platform for 2 instruments, 1 Shading disk mechanism, 1 arm extension of length 160, 210 or 510 mm and a dual shading disk of diameter 63 or 90 mm. Please specify extension of the parts number ex2 = -nnn-dd, where nnn is for the arm-length 065, 070 or 1000 mm and dd = 63 or 90 is for the diameter of the shading disk.
