JMT - 559
TENSILE STRENGTH TESTER
(ELECTRICALLY OPERATED) IS : 269 - 1958, BS 12.
The instrument employs a friction - free, accurate, double level system, the load being applied by means of sliding weight on the top level. The capacity of the unit is 900kgs. After fixing the briquette in the jaws, the machine s switched on. The sliding weight slides over the calibrated level thus applying tension to the specimen. A micro-switch fitted instantly stops the machine on failure of the briquette and on failure the tensile load is accurately read to 0.5kg. by means of a marker provided on the sliding weight. The machine can be made operable for subsequent test only after the sliding weight to its zero position.
Suitable for operation on 230 volts, 50 cycles, single phase, A.C. supply.
Complete with one brass briquette mould and one base plate.
