Resistance Meter (Autoranging, Portable) – M 880

Overview:

The M 880 is a CE compliant, easy-to-use precision instrument that incorporates advanced features typically found in more expensive units. It’s engineered to test surface resistance, point-to-point, and point-to-ground resistance in accordance with commonly referenced ESD Industry specifications for packaging, flooring, worksurfaces, and other materials.

Key Features:

• Autoranging: Automatically selects the appropriate range from <10³ to >10¹² Ohms.
• Autoselect Test Voltages: Measures at 10 Volts for conductive ranges (<10⁵ Ohms) and 100 Volts for dissipative and insulative ranges (>10⁶ Ohms).
• Clear Resistance Indication: A tri-color 12-LED array (4 Green for Conductive, 6 Yellow for Static Dissipative, 2 Red for Insulative) indicates the resistance of the material in one-decade steps and characterizes it as conductive, dissipative, or insulative.
• High Accuracy: Provides measurements with an accuracy of ±10% of the mean value.
• Built-in Electrodes: Features chrome-plated parallel bar electrodes (2.5” (64mm) long, spaced 1.56” (40mm) apart) for convenient measurements.
• Auxiliary Input Jacks: Enables connection of external resistance probes (sold separately) for additional measurement flexibility. The built-in electrodes are automatically disconnected when external probes are used.
• Resistance-to-Ground (RTG) Capability: Includes a ground cable for checking RTG measurements.
• Portable and Durable: Compact design (5.0”x2.5”x1.1” / 130x65x28mm) and lightweight (8.3 oz / 230gm), housed in a vinyl carry case with all standard accessories for easy transport and protection.
• Low Battery Indication: Ensures you’re always aware of battery status.
• CE Compliant: Meets European safety standards.
• Power: Operates on a single 9-Volt alkaline battery.
