Model 823 Resistance Probe: 52 Pins, 3.0″ Measurement
The Model 823 Probe utilizes fifty-two spring-loaded pin-style gold plated electrodes to measure the resistance or resistivity of nearly any surface including non-flat samples and multi-layer laminates.
- The probe is comprised of eighteen center electrodes surrounded by thirty-four electrodes in the outer ring. The gold plated electrodes are socket mounted for easy replacement.
- Recommended Minimum Measurement size is a 3.0” (76mm) diameter surface and a 0.438” (11mm) deep cavity.
- Each electrode requires 5 oz. (688 gr.) for total compression.
Due to its’ larger size and weight, the Model 823 does not utilize the ETS Model 848 Handle Assembly.
