The Surtronic Duo is an advanced portable surface roughness gauge that can measure multiple roughness parameters at the touch of a button. These parameters, such as Ra, Rz, Rp, Rv, and Rt, are displayed on an intuitive 2.4-inch LCD color screen. The use of rechargeable batteries facilitates fast, easy, and accurate field measurements in all environments and surfaces.
