The Model 279 ISOPROBE® Electrostatic Voltmeter measures surface potential in the range of ±3000 volts without contacting the measured surface. It features high-accuracy (0.1%), drift-free measurements that are almost fully independent of probe-to-surface separation.
Its low profile design is optimized for rack mounting of multiple 279’s in a minimum space.
Side and end viewing probes accommodate various mounting requirements. Specialty high resolution probes allow the 244A to resolve spot diameters as small as 1 mm. Probes include air purge capability to prevent ingress of particulate.
