The Desco 19770 LCD Surface Resistance/Resistivity Test Kit is a portable instrument designed to measure resistance between two points (RTT), surface to ground (RTG), and surface resistivity in accordance with ANSI EOS/ESD Association Standard S4.1. The unit’s unique Liquid Crystal Display (LCD) allows the user to easily read measurements directly from the meter. This unit is ideally suited for evaluating the electrical properties of ESD protective work surfaces and flooring products. The meter incorporates two parallel probes on the bottom of the unit which allows surface resistivity measurements. These parallel electrodes allow for quick and easy testing of a variety of surfaces and materials, without the use of 5 pound electrodes. The 5-pound electrodes (item 50003), and test leads (item 50075) can be bought separately. Specifications. Ranges: 10^3 to 10^11 ohms @ 10 Volts, 10^6 to 10^12 ohms @ 100 Volts.
