Federal Snow Sampling Tubes

The Mt. Rose or "Federal" type sampler is a professional grade snow sampler based on USFS design criteria. This set measures snow depth and water content to determine snow density. Sensitive spring balance is graduated in both equivalent inches and centimeters of water. The sampler is made with Cutter I.D. of 1.554in and 1.625in (4.13 cm) I.D. anodized aluminum material.

The sampler can be specified in English or metric units with the standard USFS length in 30" long sections and the metric in 1 meter sections. The tubes are precision machined to a very specific volume for accurate water equivalent measurements. The standard sets can be ordered with up to eight sections. The standard Federal cutter is a 16 tooth weighing 3 oz. and is typically used for sampling up to 30 feet deep.

The McCall type sampler is a heavy walled aluminum snow tube that has been designed for deeper sampling than 30 feet or with layers of heavy ice. The cutter is also heavy duty and is hardened and ground acme threaded steel weighing 6oz.

Product Features

• The McCall tubes also feature ACME threads internal to the tube so that no externally connected couplings are attached to the tube. This allows heavier threads and a smooth external tube to allow deeper penetration into the snow pack.
• The McCall tubes are available in English and metric sizes.

Due to current supply chain issues, McCall tubes are not currently available.  This impacts McCall tubes only, standard Federal tubes are readily available.
