Model 135G

Same as 135, but with granite base which has greater resistance to wear, lower thermal coefficient and freedom from rust and corrosion. Flatness certified to within .000050”.

Model 135W

Same as model 135 except that indicator is equipped with dead weight and contact point to meet a particular ASTM or TAPPI specification for checking compressible materials. When ordering, specify weight load, contact and shape. If granite base is desired, specify Model 135GW.
