Electrostatic Voltmeter - Isoprobe® - model 244A

Pictures | Documents | Probes and Accessories


The model 244A 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. It enjoys a proven record and long, successful history in both laboratory and manufacturing environments.

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.
