TOPCON dl-502 electronic level

  Product description , Dl-500 adopts advanced Rab random bidirectional coding technology and optimized digital processing algorithm, which can quickly obtain stable and reliable observation values and accuracy even in changeable environment; Even when there is partial shadow on the surface of the scale or the brightness is lower than 20lux, the dl-500 can immediately display reliable observation values as long as you gently press the measurement key; The airborne leveling program meets the requirements of national leveling specifications and can complete various leveling and calculations
The observation data in the memory can be directly downloaded to the computer for calculation and processing, which eliminates human errors in the process of data recording
