Product Description

Digital Color Screen Portable Durometer Leeb Hardness Tester For Metal Steel
Digital Color Screen Portable Durometer Leeb Hardness Tester for Metal Steel


 

1 General description

1.1 Features 

l Color display (320×240 TFT) with adjustable backlight

l Converts to all common hardness scales (HV ,HB,HRC,HRB,HRA,HS), and real time display HL value.

l Probe plug and test. Support hot plug, the probe can be set automatically and automatic recognition function.

l Built in high capacity rechargeable lithium battery and charging control circuit. Continuous working period of no less than 150 hours.

l Instrument with automatic sleep, automatic shutdown and other power saving features.

l Menu operating, the operation is easy and convenient.

l With USB interface can be convenient, fast data exchange and parameter settings.

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 500 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 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 Thermal printer integrated, convenient for in field printing.

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.

 

1.2 Main Application and Testing Range

1.2.1 Main Application

l The assembled machinery and permanently installed parts

l Die cavity of molds

l Heavy work piece

l Failure analysis of pressure vessel, steam turbo-generator set and other equipment

l Narrow testing space where work piece installed

l Bearings and other parts

l Cases which require the test result with normalized original recording

l Material identification of the metal material warehouse

l Quick tests of large range and multipoint measuring positions for heavy workpiece
