Digital Multimeter


Professional T-RMS Industrial Multimeter

DT-9939

These are new professional multimeters with triple LCD Backlit Displays. They provide very safe measurements with double moulded plastic housing and are have ingress protection 67 to make it water proof. The high performance with data logging capabilities and more display options makes it a very versatile instrument. They all confirm to EN61010-1 CAT IV 600V / CAT-III 1000V. The meters being T-RMS can be used at site for accurate measurements. They have high resolution 50,000 and 40,000 counts display combined with analogue bargraph, with basic accuracy of 0.03% and 0.06% makes it usable at very wide areas of application. The backlit LCD makes is usable even in dark environments.
