The Brooks-Range Snow Crystal Card Pro is the perfect tool for studying snow. Expansive 1mm, 2mm and 3mm grids are laser etched for precision when estimating snow crystal sizes.
4½” x 7” (11.4 x 17.8 cm)
Because each grid has a textured, anodized flat black surface, crystals stay put and a degree of relief is achieved.
Has a low thermal conductivity to minimize melting and preserve the crystals
Dimensions and guidelines for performing Rutschblock, Stuffblock, Compression, and Shovel Shear Tests are etched on the backside.
Snow crystal terminology is etched on the front side to aid in proper recording of conditions in a field book.
By using the attached string and weight, the Snow Crystal Card doubles as an inclinometer with one-degree increments of resolution.
Inclinometer string and instructions included
