When it is necessary to collect a sample of dry material such as grain, corn, pellets, etc. at a specific depth, The NASCO Dry Depth Sampler will get the job done. The unique sampler head is screwed onto the end of a 6ft., 1.83m adjustable alumunium pole that extends to 10ft., 3.05m. Adjust the pole to the correct lenght, and push the sampler down into the materials allowing it to flow through the collection head untill the proper depth has been reached. As the sampler is pulled out of the material, the end flap closes and the sample stays inside. turn the sampler sligthly to empty the contents into a WhirlPak bag or other suitable container.
