CONTAX D-8043 SO MID is the new static meter with direct insertion, for measuring active energy in a three-phase system with a maximum current of 80 A, MID approved. As is known, compliance with the MID Measuring Instruments Directive guarantees a high level of metrological protection so that the parties can consider the measurement result reliable. In fact, the Directive establishes that the design and manufacture of the instrument must be of high quality as regards the measurement technologies and the security of the data to be measured. The new meter, which has a measurement accuracy index defined in class B, stands out for its large backlit LCD display, the largest in its category, with 6 digits for reading integer values + 2 digits for decimals. Below the display, there are also three LEDs that indicate the presence of the load in each of the phases and an optical pulse output, with a constant of 800 pulses per KWh. The meter is equipped with a pulse output
