Description
- The SJ-603 Inclinometer System is designed for measuring horizontal ground displacement.
- It features a large LCD screen with backlight, making power usage and readings easy to view and operate, along with a directory menu function for convenient operation and user-friendly control.
- Compared to conventional measuring devices, it is smaller and lighter, allowing excellent portability. The power supply automatically turns off if the device is not used for more than 10 minutes.
- In addition, unlike previous models that required separate communication cables for each component, the Indicator-Read Cable and Indicator-Enter Key communications have been made wireless to enhance portability and ease of measurement.
