The PD-I and PD-E range meters feature a digital level and inclination sensors that simplify complex measuring tasks. The screen can be clearly read even in bright sunlight, and the intuitive user interface makes operation remarkably simple. While the PD-I model is particularly suitable for indoor applications and capable of measuring distances down to 0 mm, the PD-E model has been designed for outdoor measuring. It achieves accurate results very quickly, especially over long distances.
