The water level gauge can also be updated! It measures the relative displacement between the observation well's pipe and the surrounding ground.
The "GEH-250S" is a ground subsidence gauge that can measure subsidence (uplift) of up to 250mm with high precision of less than 0.1mm, allowing for long-term stable measurements. It measures the relative displacement between the pipe of the observation well at a fixed point and the surrounding ground. Additionally, because it uses a non-contact magnetic sensor, it can measure even in outdoor environments exposed to wind and rain, as well as in high-humidity underground pits. By replacing traditional self-recording ground subsidence gauges, it is expected to reduce the labor involved in paper replacement and data reading. 【Features】 ■ High precision of less than 0.1mm, allowing for long-term stable measurements ■ Utilizes a non-contact magnetic sensor ■ Capable of measuring in outdoor environments exposed to wind and rain, as well as in high-humidity underground pits ■ Low power consumption with a 12V power supply ■ Can be combined with a compact logger and powered by solar cells and batteries for long-term operation *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Measurement Examples】 ■ Beam-type Settlement Gauge - A common method for observing the displacement of observation wells (fixed points) using fixed horizontal beams such as H-beams as reference points. ■ Beam-type Settlement Gauge (Multi-Channel Type) - Displacement is observed at different depths by taking measurements from a fixed horizontal beam such as an H-beam with a common reference point. ■ Slab Reference Method Settlement Gauge - A simple method for observing the displacement of observation wells (fixed points) using the ground near the observation well (concrete ground) as the reference point. *For more details, please refer to the PDF document or feel free to contact us.
