The Pica Powder Spraymarker is an innovative marking tool for contactless and precise marking of drill holes. The system employs green fluorescent powder-based chalk and enables precise marking through drill holes. A 360° spray arm ensures that even hard-to-reach areas can be reached with ease. The markings adhere reliably to all surfaces. With a service life of up to 1,500 spraying cycles and the option of refilling, the device is designed for long-term use. Integrated dust and moisture protection supports functionality under demanding construction site conditions.
