HTD 4000 is used to measure case depth and is capable of verifying case depths ranging from 0.4mm (16 thou) up to a maximum of 2.5 / 2.8mm (100110 thou). Our system utilizes a new and very advanced principle based on the continuous measurement of the electrical resistance in relation to the working load applied. Our design meets the demands of the heat treatment industry. HTD 4000 is equipped with a big stand to enable the testing of large work pieces having overall dimensions up to 550mm (22") in height and 350mm (13.8") depth
The HTD 4000 is also designed for hard to reach areas and testing under extreme conditions, yet requires very low maintenance. The diamond penetrator lasts up to 1500-2000 tests before recoating, depending on the hardness of the test piece and maximum working load being used.
QT-HTD1500 is a case depth analysis testers that checks case depth (and core hardness) up to 1.3mm (0.050inch) without sample sectioning therefore not being destructive for the test piece. QT-HTD1500 operates by a continuous depth of indentation measurement process while the force is steadily increased. The electronics calculate the hardness based on the displacement, depth, and force applied. The unique test surface referencing capabilities of the testers allows this depth measurement process to be very accurate even with slight deflection under the high forces involved up to 1500kgf.
QT-HTD1500 is designed to meet the needs of the case depth measurements, it has a stand with large capacity and is therefore suitable for testing large pieces. No particular maintenance is required. Designed to work in critical environments.
