- Measure in any direction with auto angle detection
- CalTag technology on impact devices and probes
- Graphical representations and statistics
- Rechargeable batteries
- Aluminum enclose with rubber sides
- Programmable quick access key
- Send data via Bluetooth
- Color backlight alphanumeric LCD display

DataCenter is software used to transfer and process data stored in the unit memory. With the tools in
DataCenter you can generate statistics, graphics, export data to other programs and prepare custom reports.
With the QH7 measurements can be transferred using a USB cable and or by Bluetooth.
