[ Higher Model Rockwell Hardness Tester KHT800-M/KHT800-A Product details]:
Verticaltest height of 430mm and throat depth of 220mm.:220mm;
For KHT800-M and KHT-800-A model;

KHT800-M is a new designed, advanced Automatic Rockwell Hardness Tester, which combine similar function with stable design, It is made with Manual handle wheel pre-load,automatic main-load and testing cycle. The tester’s shape islintegrated casting body with more wide basement leads to permanent stability. Manual pre-load will be more fit users’ operational request.
 


New features:

• The test force are applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit instead of traditional dead weights. The result is highly accurate measurements at all test loads up to 0.5%;
• Simple plug - and - play tech allows for much more quick and easy installation than traditional weights type machine;
• Manual handle wheel pre-load. Automatic main-load and testing cycle;
• Extended dolphin nose allows verticaltest height of 430mm and throat depth of 220mm;
• Integrated casting body with more wide basement leads to permanent stability;
• RS232 and USB port to PC;

 
 

Basic functions:

• Regular Rockwell hardness tester for metal and plastic material;
• Horizontal protrudent Indenter Design, suitable also for internal and external testing;
• Testing on Surfaces difficult to reach. Testing internal surface of rings and tubes;
• Provided with many features such as high measuring precision, wide measuring range with 15 Rockwell scales;
• The tester is suitable for testing of carbon steel, alloy steel, cast iron, non ferrous metal;
• Automatic testing cycle: Lifting of part, pre-loading, loading, dwell, unloading, results will be finished automatically;
• Measuring results digitally displaying and can be printed, or transmitted to external computer automatically by USB port;
