Model 4240N GENUINE GURLEY High Pressure Densometer

This model is identical in function to No. 4150 and includes the weighted arm assembly found on No. 4250. Uniform dead-weight clamping pressure for tests is supplied by the unweighted lever arm or by the addition of either 0.34 lb. (optional) or 2.0 lb. (standard) weights. These combinations produce clamping pressures of 3.2 psi, 9.6 psi and 40.5 psi respectively. With the addition of the smoothness test plate, a paper punch. 0.34 lb. weight and storage box, the No. 4240 becomes a no. 4250. Order the digital timer and base separately.
