HTD-4000 - Qualitest International Inc.

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
