Electric Universal Penetrometer

The electric universal penetrometer is a direct-reading instrument for precision penetration measurements of bituminous materials and cement. Its automatic digital timer has a release mechanism that is switchable between seconds, minutes and hours. Set in 1/10th second intervals.  The plunger releases with a push of a button and automatically stops after the preset time durations.  Each unit has a 5″ diameter indicator dial, graduated in 400 divisions of 0.1mm, corresponding to 40mm penetration. Preset to zero to eliminate errors.  Includes a 47.5g plunger with 3.2mm hold and two loading weights (50g and 100g).
