Gossen Metrawatt METRAOHM 413 Ohmmeter, 200 Ω Max, 10mΩ Resolution

The Gossen Metrawatt digital ohmmeter is a battery-powered instrument for the measurement of low-value resistances up to 200ohm in electrical systems. Large protective conductor, earthing, equipotential bonding and lightning protection systems can also be tested quickly and safely with the help of this device. Resistance is measured between reference earth (e.g. an equipotential bonding strip) and any desired points to this end. A measuring current rating of 200mA (in the 20ohm range) and automatic functions assure reliable measuring results.
