Title: [Solved] Help needed to decide between a Brymen BM257S and BM235
Post by: HoracioDos on April 12, 2017, 01:37:42 pm

Hello!

I want to buy a second DMM to replace a Mastech 830. I already have a Brymen BM235 and I'm so happy with it that I can't decide between a second BM235 or a BM257S. I don't know if It won't be wise to buy two identical units if the BM237s costs only $20 more. 

I've been reading the specs and if I understood them correctly, the BM237 seems to be a little bit more accurate in some aspects. I would like to build my own interface based on this thread in the future.

So I'll appreciate any thought that helps me to decide.

Thanks in advance.

I find the bar graph on the 257/s is a very useful feature
I find the orange backlight of the 257/s less sexy than blue of the 235 (or Daves one at least) not sure about the non EEVblog branded ones

Well, if you want the PC interface, you need the 257. Or hack the hell out of the 235.
