PHR series portable rockwell hardness
Almost
* PHR series portable rockwell hardness is durometers manufacturing technology progress. The hardness tester tests on the precision, conditions, lightweight miniaturization. Weight only common desktop rockwell hardness of one percent, the minimum weight 0.7 kilograms.
* PHR series portable rockwell hardness testing projects include soft aluminum, zinc, lead and tin, gold, silver, copper alloy and the medium hardness and copper alloys, low carbon steel, stainless steel, titanium and very hard hardened steel, deep carburizing steels, hard alloy, covered almost all common metal.
This los hardometer creasing small, but as a nondestructive testing workpiece directly.
This los hardometer, flexible operation. Can use as micrometer. All sorts of small size of metal parts and the boss, bring inconvenience mobile rods, tubes, large materials can test, the application scope is very promising. Suitable for batch processing instruments or semi-finished product package workpiece do, can be used for production, sales field and material warehouse.
This program can be directly rockwell hardness test tubes hardness, also can test tube wall rigidity.
This los hardometer 5 types, sample size is the most big mm, 50, and 200mm 100mm.
* rockwell hardness value can be converted by querying data (proposed.and), brinell hardness value (HB) or tensile strength (b) value σ.

Instrument selection
The hardness tester PHR series model is based on maximum size and open about instrument rockwell hardness projects/surface rockwell hardness of classification. "PHR -" behind the number of opening size (inches), the letter "S" surface rockwell hardness, letters, "said ST" pipe surface rockwell hardness. Users can according to the size of the test sample were, choosing the appropriate type of instrument.
