  • Why Buy From Delta Pro Meters & Measurement

    Gossen Metrawatt M227C and Avionic Set METRAHIT 27AS, Insulation and Milliohmeter

    When only the best will do, and you need professional specialised measurement.

    The METRAHIT 27AS Avionic set is an avionics test kit that includes the METRAHIT 27I.  Ideal for use in avionics technology, field service, and repair.

    The german-made MetraHit 27I is a milliohmmeter, multimeter and data logger all in one, with insulation testing capabilities, up through the gigaohm range.  It 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 27I is used for service and repair work performed on airplane and helicopter electrical systems (voltage, insulation, milliohm and temperature measurement). In addition to its own multimeter functions for electrical quantities, the instrument also includes a mega-ohm measuring function with insulation test voltages of 50, 100, 250 and 500 V, as well as temperature measurement with Pt100 and Pt1000 sensors.

      Man overwhelmed by choice of multimeters

       

      Confused?

      Overwhelmed?

      It’s one thing to know what basic functions you require of a multimeter - Voltage, Current, Resistance, Capacitance, Temperature etc.  It’s another thing to nut through all the specifications and understand exactly what your multimeter is capable of.

      A lot of the time you only need to know the course parameters of each measurement,  e.g. up to 1000A current,  600V voltage,  1 mega-ohm resistance etc.  But sometimes, particularly in industrial applications, you need to know how your multimeter performs a particular test, how accurate the displayed results are, and whether or not the multimeter will be safe and reliable for the intended application. 

      This is where terms such as count, range, resolution, basic accuracy, IP rating, CAT rating, True RMS, crest factor and others come into play. 

      If you are not familiar with these terms and how they relate to multimeter measurement, Steve has put together a series of blogs to explain in laymen’s terms what each mean.
