产品介绍
"The METRAHIT 27M is a milli ohmmeter from Gossen Metrawatt.","Features:","Accessories:","Applications:","The METRAHIT 27M is a compact, rugged and reliable instrument, which is equally suitable for precision measuring and recording tasks in the factory, for on-site service and in the laboratory:","The Gossen Metrawatt METRA HIT 27M is a compact milliohm resistance meter plus multimeter and thermometer for the measurement of low-value contact resistance on aircraft outer skins (lightning protection, wick test), and for general low-resistance measurements. The METRAHIT 27M milliohm resistance meters are the modern alternative for the well known TH2 (Thomson) and Wh2 (Wheatstone) measuring bridges. They provide an expanded measuring range, greater accuracy and easier reading. As universal measuring and test instruments, they acquire and record values to an integrated memory module including resistance in the milliohm and micro-ohm ranges, as well as normal multimeter resistance values in the ohm to mega-ohm ranges by feeding a measuring current to the resistor, conductor or contact under test. The respective measuring current is determined by the rotary selector switch setting and lies within a range of 1 to 0.02 A in the milliohm ranges."
