Digital Plastic Rockwell Hardness Tester JHR-150P
Brief Introductions:
Brief Introductions:
JHR-150P is an effective automatic digital plastic Rockwell testing machine with high accuracy, reliability and durability, it is applied at the workshops and measurement departments for determining the Rockwell hardness of the hard rubber and plastic.
Instrument Features:
Instrument Features:
● JHR-150P is a half automatic and intelligent hardness testing machine, except to lift up the anvil to touch the specimen and select the test force: 60Kgf(588.4N), and 100Kgf(980.7N) in hand-knob manually, the other operations are entirely automatic.
● The testing force, the process of loading, dwell and unloading, the hardness testing value, and the corresponding converted scale are displayed on LCD screen automatically.
● JHR-150P system will remind the operator of select the corresponding testing force and indenter after scales choosing, and the automatic hardness testing and digital 0.1HR resolution display, which avoids the man-made error and enhance the measuring accuracy.
● JHR-150P hardness conversion among 14 hardness scales: HRA, HRB, HRC, HRD, HRF,HV, HK, HBW, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, it doesn’t need the operator to trace and check the fussy hardness comparison table again.
● JHR-150P saves, displays and analyzes the value of maximum, minimum, average and tolerance automatically, the mini-printer prints the main measuring data automatically, and it supports PC communication in RS232 interface and cable.
