D2 high precision digital level (Stonex)

high accuracy digital level
Stonex D2 digital level is the right solution to use when you need to measure gradients or height with better precision compared to GPS systems. GPS systems normally provide accurate measuring on plane (horizontal) but not in vertical direction, due to the position of satellites, all on the same side of sky compared to the GPS receiver

DESCRIPTION
To use together with a barcoded stadia for high precision measurements, the Digital Level D2 provides an height accuracy of 0,7mm/Km. This makes the D2 an ideal level not only for high order levelling but also deformation measurements and precise surveying, as well as general construction. The onboard adjustment program, height difference calculator, inverse staff measuring mode, in combination with various measuring configurations enable you to execute all calculation.

Key Features:
The internal memory can store up to 2000 measures (points) that can be downloaded on a computer by an RS232 serial port
Easy to transport
Water and dust protected and allow long operation on field (about 16 hours).
