Model 841 Resistance Probe: 8 Pins, 0.5″ Measurement

Overview:

The Model 841 Probe utilizes eight spring-loaded pin-style gold plated electrodes to measure the resistance or resistivity of nearly any surface including measuring samples as small as 0.5″ (13mm) diameter, non-flat samples or small areas on large samples.

Features:

• The probe is comprised of one center electrode surrounded by seven electrodes in the outer ring. The gold plated electrodes are socket mounted for easy replacement.
• Recommended Minimum Measurement size is a 0.5” (13mm) diameter surface and a 0.438” (11mm) deep cavity.
• Each electrode requires 5 oz. (688 gr.) for total compression.

The Model 841 is designed to be used with the ETS Model 848 Universal Handle Assembly.
