YHT500 Portable Hardness Tester
Features
l Color display (320×240 TFT) with adjustable backlight.
l Add four new hardness scales, HRA, HB for D impact device of alloy tool steel; HV for cast aluminum alloy
l Add New user material function, to meet the need of user can test the special material.
l Converts to all common hardness scales (HV, HB, HRC, HRB, HRA, HS).
l English displaying and menu operating, the operation is easy and convenient.
l With USB interface, multiple communication modes are adopted to meet customized requirements of various users.
l Equipped with 7 types of impact devices which need not to be recalibrated when changing them, the system can identify the type of impact device automatically.
l Max 600 groups（impact times:32-1）of data can be stored at internal non volatile data storage.
l Upper and lower limit of hardness can be preset; When the tested value exceeds the limits, alarm will send out automatically to make convenient for the requirements of batch measurements.
l Back light display has been used to make convenient for the use in poor light.
l Test values software calibration function.
l Material of “cast steel” is added; HB values can be read out directly when D/DC impact device is used to measure “cast steel” work piece.
l Printer be separated from main unit and copies of testing results can be printed as required.
l Using lithiumion rechargeable batteries, Continuous working period: approx. 200 h (no back light on).
l Software of PC can be installed according to the requirements of user, the function will be more powerful to satisfy the more strict demands of quality control and management.
