Model 244A Electrostatic Voltmeters measures surface potential of insulating, semiconductive or conductive materials on a small 0.04” (1mm) diameter spot or over a large area using patented techniques which assure high-accuracy drift-free measurements almost independent of probe/surface separation.
- Measurement Without Physical Contact
- Accuracy Better Than 0.1% at Almost any Probe-to-Surface Spacing
- Full Complement of State-of-the-art High Ferquency Probes
- Provision for Master/Slave Operation
