It is a railway-specific measuring instrument used to measure the spatial parameters of electrified line catenary systems and related equipment that provide support and positioning for the catenary. It features a split waterproof design, a detachable battery, and utilizes high-precision laser distance measurement, displacement sensors, and high-definition cameras for non-contact measurement. The main unit can rotate freely around its axis to meet the measurement needs of various catenary equipment.
Complies with the standard "JJG (Railway) 150-2020 Verification Regulation for Catenary Geometry Parameter Measuring Instruments."
