Pocket Concrete Penetrometer
It is a versatile quick and handy instrument for evaluation of ‘Initial Set’ of concrete mortar both in the laboratory as well as in the field.
The instrument consists of a barrel and sleeve enclosing a calibrated spring. The barrel is graduated from 0 to 50 kg/sq cm and carries a friction ring which acts as a cursor. The penetration needle of 0.3 sq. cm sectional area, is an integral part of the barrel and is marked at 25 mm from the end.
In operation the plunger is pushed into the concrete mortar upto the marked line and the penetration resistance offered by the concrete mortar is directly indicated on the barrel in kg/sq.cm. The ‘INITIAL SET” is considered to have been reached when the penetration resistance offered by the mortar is 35 kg/sq.cm.
Supplied complete in a carrying case.
