MAX Elite™ Electrometer part of complete solution for: Stereotactic Absolute Dosimetry CyberKnife

MAX Elite™ Electrometer Overview

The choice for precision. The standard for quality.

  • Get up and running quickly with an intuitive interface that makes measurements and adjustments seamless.
  • The largest capacitive touch screen on the market delivers quick, responsive touch control—no stylus needed.
  • Fast-settling and fast-zeroing features that deliver both speed and precision for quick, reliable data collection.
  • Make use of the remote operation capability or set your optimal screen angle for maximum viewing flexibility.

The foundation for evolving technologies

This electrometer isn’t just a device—it's the foundational platform for tomorrow’s advancements. Engineered to integrate new technologies and support emerging therapies, it delivers unmatched precision and flexibility through cutting-edge technology. Unlock new possibilities in care with a tool designed to evolve alongside you.

From Data Matrix to Database in Seconds

Say goodbye to manual data entry! The advanced camera system scans the data matrix code (DMC) on your chamber's calibration certificate and instantly auto-fills key detector details—calibration factor, date, name, and serial number—directly into your database.

*Not available in some markets. Feature availability may be limited per channel configuration.

*Patent Pending.
