  • Safety Concerns with Contact Tachometer

    Safety Concerns with Contact Tachometer
    Nidec-Shimpo presented the DT-207LR-S12 Digital Tachometer with included 12-inch circumference wheel and robust aluminum housing. With the additional size of the 12-inch wheel they could more than triple their hand's distance from the machinery and greatly lessen the chance of injury. Plus, due to the larger size body of the Shimpo tachometer than the previous mini-tachometer used, their hands were more readily able to properly grip the ...

    Strontium in plagioclase revealed by QUANTAX WDS for SEM
    Trace elements and their spatial distribution in rocks and minerals are of substantial interest to geoscientists: for example in igneous rocks, trace elements are valuable tracers for magma sources and geological processes affecting the subsequent evolution of magma. Electronbeam techniques using WDS are state-of-the-art tools for such in-situ investigations.
