Details

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.

Review by Joachim T 
Posted on 05/11/2021
I bought this multimeter for "whatever comes across my desk" at work. I started out by looking at a famous yellow supplier of multimeters, but the performance to price ratio was better on the BM789 so I ended up buying the Brymen.
The product itself feels solid and has a nice size (it does not feel as chunky as the BM8XX series which I also have experience with. The weirdly oversized "head" on the BM8XX is gone so a big thumbs up for that).
The functionality is great, and the multimeter is intuitive to use, once you have spent some time pressing the buttons and seen how to get into different measurement modes.

If I should mention anything negative, then I would have preferred that the multimeter used 9V batteries and that it supported datalogging over IR as this is something we use on other multimeters at work.

But in general, I am really satisfied and would highly recommend it for anyone looking for a multipurpose meter.
