銷售Fowler Digital Rockwell Hardness Tester 硬度檢測(cè)儀
Fowler公司始建于1946年，現(xiàn)已發(fā)展到全國(guó)及波士頓、芝加哥和加拿大安大略省。Fowler是生產(chǎn)測(cè)量器具的專業(yè)制造商，Fowler已經(jīng)成為一個(gè)主要的力量在這密電子工具領(lǐng)域。Fowler公司的產(chǎn)品包括精密工具、電子測(cè)量?jī)x器、光學(xué)測(cè)量工具、量具校準(zhǔn)設(shè)備及硬度的測(cè)試設(shè)備。
Mechanically operatede with an electro-mechanical readout, the instrument utilizes a series of special preloaded springs, providing a load of approx 15kg to the indentor
• Capable of setting upper and lower limits for OK/NG display
• It's virtually impossible to overload or influence readings by varying hand pressure
• When conducting a hardness test, the springs operating against the diamond assembly are balanced against the hardness of the specimen. The harder the material under test, the more movement is effected between the diamond point and the datum face of the unit. This movement is interpreted by a specially calibrated linear displacement transducer which encodes the linear movement of the diamond and transmits it to the electronics, where the hardness value is produced as a digital readout
Maximum penetration of diamond into the specimen is .005"/.125mm
• Check calibration against supplied reference book
• Tester weighs approx 5 lb/2.25 kg
• For accurate readings, avoid coarse finishes on machined surfaces. Specimines to be tested must be free of rust and scales.
• Zero setting is achieved by gently depressing the hand grips until digital readout switches on. When movement ends, the reading is taken. Automatically shuts off when hand grip is released.
• Operates on a 9 volt battery （approx life of two years）. End of battery life is signalled by 'LOW-BATT' in corner of the display
• Price includes calibrated test block, indentor key, instruction book and deluxe fitted wood case 。
