Description
This two-point resistance probe from DESCO, Desco 19297, is designed for measuring surface resistance on small samples or small areas. The Desco 19297 uses two gold-plated, spring-loaded needles with conductive rubber electrodes to ensure contact on small or non-planar surfaces. The probe comes with a BNC/banana jack adapter and is specified as compatible with several Desco surface resistance meters.Design and function
- Two gold-plated, spring-loaded needles with conductive rubber electrodes
- Electrode diameter: 3.2 mm; center-to-center distance between electrodes: 6.4 mm
- Includes BNC/banana jack adapter for connection to a resistance meter
- Meets ANSI/ESD STM11.13-2021 (as stated in the manufacturer's technical bulletin)
Operation
- Connect the probe to a compatible resistance meter via the included BNC adapter and the meter's test leads.
- Place the sample on an insulating surface.
- Press the spring-loaded needles down approximately half of their travel; avoid touching the metal parts with your skin.
- Take the measurement with the resistance meter.
Typical Applications
The Desco 19297 is used for measuring surface resistance on small samples or small areas on a larger sample, as stated in the manufacturer's technical bulletin.Documentation
