Model 850 – Surface Resistance Probe Electrode


Protect Your Electrostatic Discharge Susceptible Items by ensuring your ESD prevention is working. Electro-tech system’s Model 850 resistance electrode probe provides you with ability to measure resistance employing both point-to-ground (RTG) and point-to-point (RTT). The 850 is designed to measure the resistance of any planar surface. The probe can be used to make measurements on floors, mats, workbenches, garments, seating or any other flat surface where the resistance between two points is required.  When integrated with the ETS 871 Wide Range Resistance Meter, resistance values can be seamlessly read.
