The model 244AK ISOPROBE® Electrostatic Voltmeter measures surface potential in the range of ±2600 volts without contacting the measured surface. It features a 200:1 output ratio and high-accuracy (0.1%), drift-free measurements that are almost fully independent of probe-to-surface separation.
Side- and end-viewing probes accommodate various mounting requirements. Specialty high-resolution probes allow the 244AK to resolve spot diameters as small as 1 mm. Probes include air purge capability to prevent ingress of particulate.
