Our QH7 HEAVY-DUTY Leeb hardness testers use DMQ impact devices with CalTag technology so that you don’t have to calibrate the unit when changing devices and GyroTag technology so that the impact angle is automatically recognized.
All QH7 models include rechargeable batteries and a Data Logger to store 32000+ measurements that can be transferred to a PC via Bluetooth o USB using DMQ DataCenter software.
