Granutools is proud to introduce the GranuCharge At Line (AL), a breakthrough instrument designed to measure electrostatic charges in powders during flow in real time and directly on the production line. Electrostatic charging is a common challenge in powder processing industries such as pharmaceuticals, additive manufacturing, and metal powders handling. This phenomenon affects powder flowability, causes handling difficulties, and can even present safety risks.

Real-Time Electrostatic Monitoring, at Your Process
Unlike traditional lab-based methods, the GranuCharge AL provides instant access to the charge per mass measurement thanks to its integrated load cell combined with a Faraday cup connected to a highly sensitive electrometer. As powder flows through the process and into the device, the GranuCharge AL automatically captures the electrostatic charge accumulated, delivering high-precision results with minimal setup, all without stopping production.
Applications That Make a Difference
Pharmaceutical Continuous Manufacturing: Assess how equipment such as hoppers, feeders, and blenders influence electrostatic charge accumulation to optimize material handling and process design.
Additive Manufacturing & Metal Powders: Monitor charge effects on powder spreadability in powder bed fusion systems or during nozzle flow in Directed Energy Deposition (DED), helping improve powder bed quality and process reliability.
Electrostatic Troubleshooting: Identify charge build-up hotspots on production lines in real time, enabling swift corrective actions without interrupting operations.
