Indicates Surface Resistance per ANSI/ESD STM.11 and ASTM D-257
The ESI-870 Resistance/Resistivity Indicator is an LED indicating, wide range resistance measurement instrument with broad application flexibility.

It measures surface resistance in accordance with ANSI/ESD STM11.11, surface resistivity in accordance with ASTM D-257, resistance to ground and resistance point to point.

Repeatable Measurements is Key
This meter gives simple, repeatable measurements to indicate whether a material is conductive, static dissipative or insulative. The ESI-870 employs parallel bar sensing and features an easy to read LED light scale to measure a wide variety of ESD materials and equipment.

An Affordable and Reliable Tester
Save on your expenses by using this easy to read ESD test equipment instead of hiring outside help. The ESI-870 provides you with reliable results that you can trust. Avoid damage to your working materials, make sure they are safe, and secure with this useful tool.

When working with hardware or electrical components you want to ensure that you are using the proper ESD tools to protect it. Left unprotected your electrical materials are subject to being damaged beyond repair. To protect your items and successful operate on them, prevention is the key.
