Case-Depth Hardness Tester

The heavy-duty HTD 4000 case-depth hardness tester allows for case depths of up to 2.8 mm to be measured by one single indentation. HTD 4000 is used to measure case depth and is capable of verifying case depths ranging from 0.4 mm up to a maximum of 2.5/2.8 mm. It utilizes a new and advanced principle based on the continuous measurement of the electrical resistance in relation to the working load applied. The design meets the demands of the heat-treatment industry. HTD 4000 is equipped with a big stand to enable the testing of large workpieces having overall dimensions up to 550 mm in height and 350 mm in depth. It is also designed for hard-to-reach areas and testing under extreme conditions.
