Schneewaage-HIM150

The snow probe HIM 150-50 to measure snow depth and snow water equivalent consists of a sampling cylinder, a turning device, a suspension, with the rod and the transport packaging. The sampling cylinder has cm² a length of 150 cm and a cross section of 25th The cylinder is made of glass fiber laminate and provided with a metal crown. The probe rod aluminum tube is provided with a scale and a circular slide for upsetting of the snow and its removal from the sampling cylinder.

 The turning device is used according to the By plugging the sampling cylinder for rotating and pressing in the snow removal. The suspension is designed for weighing the cylinder in a horizontal position. The transport packaging is rubber coated.

The total weight of snow probe is about 2.2 kg. The collecting cylinder weighs about 1.3 kg.

For weighing the snow arbitrary scales can be used with a minimum sensitivity of 10 g. (Not included)

Methods for measuring the snow height: The probe rod inserted upright in the snow and to reach the ground, snow depth is at its scale read.

Method of measuring the water equivalent of snow:

The sampling cylinder is drilled in a vertical position with bilateral rotation and sufficient pressure by means of the turning device and, after reaching the bottom, the depth of snow is read. Depending on the needs of the full cylinder is withdrawn, or the snow is compacted slightly before pulling out, visually reaching the surface is checked and using the suspension is weighed in a horizontal position. Digital scales are equipped with the tare function, and mechanical scales can be balanced, and subtract the weight of the empty sampling cylinder. Since the cross-sectional area of ​​the crown is 25 cm, corresponding to a weight of 10 g a water equivalent of 2 mm. Practically the water equivalent of snow is calculated in mm, so that the weight is calculated in kilograms to two decimal places, irrespective of the decimal is multiplied by two.

 Thereafter, the sampling cylinder is with the crown turned up and emptied by tapping with the turning device.

 If one can not push with a force of 200 N in the soil the sampling cylinder during rotation, is no snow in the sampling cylinder, but is compressed and expressed outside the cylinder. Therefore, the cylinder is pulled out, weighed and inserted again after emptying and the extraction continued until reaching the bottom. Thereafter, the sampling cylinder is weighed again and the calculated water equivalent of the sum of the two weights. The same method can be applied to snow depths over 1.5 m after the top layer of snow was removed.

The set is made of stainless material and does not require maintenance after use is advisable to let it dry. Hard ground can cause deformation of the crown, the edges should be sanded with a file.

The delivery includes:
