The Brymen BM859s is a True-RMS digital multimeter with features such as dBm, high resolution mode, MAX-MIN, Crest and more. On the 500.000 count display of this multimeter it is possible to display extremely accurate measurements, such as DC voltage. The meter has a Crest function, which automatically displays the peak value. The display has a backlight and is therefore always easy to read. The display is updated 5 times per second with a new measurement. Furthermore, the display has an 'analogue' bar-graph that updates 60 times per second and thus clearly indicates how the measured values relate to time. The multimeter has 3 display options. The display can show 999.999 counts for frequency, 500.000 for DCV and 50.000 for other measurements. The 500.000 mode has a lower update rate of 1.25 updates per second. The 50,000 count mode is updated an average of 5 times per second. The difference with the BM857s is that the BM859s has a more accurate DCV accuracy of 0.02% and can handle more bandwidth.

This multimeter can be used with an optional PC USB connection kit! Click here!
