ASW-21 (for construction and civil engineering) Automatic Precision Leveling Table Auto Stage
This product is a device that automatically performs high-precision leveling. It is useful for maintaining the level of surveying instruments such as transits and auto-levels mounted on the top. The leveling process takes only a few seconds, which saves man-hours. In addition, the IPX4 drip-proof rating and battery operation make it suitable for use in harsh environments such as small tunnels and bridges that are inaccessible to people.
Features
01 High-precision automatic leveling after just turning on the power
02 An audible sound and LED alerts the user when leveling is complete.
03 Drip-proof (IPX4) for use in harsh environments
04 Dual power supply system with lithium-ion battery and AC adapter
05 Optional external command to start leveling can be issued.
