Reduce costs while improving measurement accuracy! Measure three underground extensometers with one device.
The "Subsurface Extensometer 3ch Data Logger" is a subsurface (vertical) extensometer developed for easy installation without the need for an external box for data collection. It simultaneously measures the expansion and contraction of the inverter wire installed underground in 3 channels. It can operate for about six months on eight alkaline D batteries and enables continuous observation during winter. It addresses concerns such as "I want to make effective use of the borehole" and "I want to install multiple points, but the cost is high." 【Features】 ■ Simultaneous monitoring and recording of 3 points ■ Low power consumption ■ Compact and lightweight for easy installation ■ Operates from -20℃ to 60℃ ■ Equipped with emergency alarm output function / compatible with web monitoring *For more details, please refer to the PDF document or feel free to contact us.

Company information
A pipe strain gauge is a product that is installed by boring into the landslide occurrence point, and it electrically detects the strain variations caused by the deformation of the pipe to measure the position and activity status of the landslide surface. Our company is one of the few specialized manufacturers of pipe strain gauges in the country, and we have received support from many customers.
