Universal digital indicator MV31


MV31 digital indicator is a universal high precision indicator designed to handle a wide range of input sensors and signals. The five-digit LED display is in a 150×139,60×34 mm to ABS housing mounting in a front panel, so that the measured values in the industrial plants can be easily read even from a great distance.
