The instrument consists of a needle attached to a spring loaded plunger, the stem of which is calibrated to read 0 to 40 kg division. Load stem is graduated at every 12.5 mm to read depth of penetration and for use with needles of larger areas. The small penetration stem is also more...
This is identical to spring type, except that the penetration pressure on the needle is conveyed through a hydraulic system to a hydraulic pressure gauge. This system permits a greater control over rate of penetration because of better visibility of load indication. Salient Featumore...
