The Brymen BM789 multimeter is a new series of multimeters in the Brymen line-up. The BM789 is perfect for customers who want more function out of their multimeters. These functions include low impedance, dBm power, and DC Loop Current 4 - 20 mA measurements. This multimeter also has a True-RMS function, which can help with measuring non-sinusoidal signals correctly. With a CATIII 1000V and a CATIV 600V rating, the meter is very robust. The multimeter can not only measure the common DC and AC voltage/current signals but is also suited for frequency, capacitance, resistance, duty cycles, and temperature measurements. This multimeter can also be used for AC+DC signals.
This multimeter also has a more economical variant with fewer functions. Namely, the Brymen BM785 multimeter. The BM785 does not have a dBm measurement, low impedance mode, DC Loop Current 4 - 20 mA verification, and a temperature measurement.
