Portable Surface Resistance Probe with LED Indicators, 9 V Battery - Desco 19301

A quick check of mats, trays, bags or tools on the production floor should not require setting up a full meter kit. The Desco 19301 Portable Surface Resistance Probe is a compact two-point probe with its own 9 V battery: place it on the material, press the button and read the order of magnitude from the coloured LED. For precision measurements Desco recommends the 19290 Digital Surface Resistance Meter.

Key benefits

• Result at a glance: colour-coded LEDs show the resistance exponent, from below 10³ to above 10¹² ohms.
• Gold-plated, spring-loaded pins with conductive rubber electrodes for dissipative materials, bare pins for conductive materials included.
• Defined geometry: 3.2 mm electrode diameter, 6.4 mm between centres.
• Runs on a 9 V alkaline battery, with a built-in pre-test check.
• NIST traceable calibration from the factory.

Applications

Quick checks of ESD control items in electronics manufacturing and handling: packaging, trays, mats, tools and small parts. The sample is placed on an insulative surface. Before each use, function is verified with an open reading (red >12 LED) and on a metal surface.
