I just bought a Brymen BM257 (actually a Greenlee rebranded version for the US market but it's the same meter) after watching Joe Smith's channel and I love it. It compares favorably to the Fluke 177 I use at work in terms of quality and performance but cost $150 instead of $400. The 257 comes with Brymen's mid-range probes, which are silicone and gold plated, really a pleasure to use.

I agree. I am a Bryman fan, myself. I have a Brymen BM257s, an excellent DMM with true (and tested) safety rating. The leads are quite good, as you say. In fact, I ordered a second pair for use in another meter I have. The leads are available on eBay from f-t-2000 (a very trusted seller) if anyone is interested in them, ebay.to/2K6P7c5.

Brymen make some great meters for a very reasonable price.

@voltlog 6 лет назад

This is my first experience with brymen meters and I've been impressed by these pocket meters.

@NoName-bt3oy 6 лет назад

The higher up the range models are a really good alternative to Fluke, especially to those living outside USA where the price of a Fluke is out of reach for non-professional users.

I'm a Brymen fan... Got 3 Brymen models from Welectron and their service is second to none! Now I'll get one of these pocket meters since they are good carry arounds and afford the input protection required from a serious meter.

@voltlog 6 лет назад

yup, in terms of protection they got it right. I will also do a voltage transient test in an upcoming video but I think they will survive just fine. I am worried about the other cheap meters though because they don't have the same level of protection.

Got a Brymen 857 and I love it.

@ozisnice 6 лет назад

Another great video. I am interested in the ruler you got.

@voltlog 6 лет назад

I think they send out one of those rulers for each order on welectron.com

You can fill up the symbols in the BM27s with paint and scrape off the access to make it visible.

@voltlog 6 лет назад

Yeah I could do that but like I said in the video I don't understand why they didn't do it in production..

Is there any reason to get the 22 over the 27s?

@SODA-iz8lc 6 лет назад

Hi Voltlog, I'm more interested in that Milli-amp tester you was showing for a split of a second. How about a video of it? I got two Brymen meters and because i don't work outside my lab,i won't buy more meters. Still it was a great video. Thanks for the upload

Nice review, but you did not get the power consumption right on the BM27s. That (electronic) relay inside the meter is used to switch a load resistor in for voltage in auto mode and it eats a lot of power, that is probably also the reason for the fast auto power off. Generally I think the ranges on the BM27s is a bit of a mess, there are too many partial duplicate ranges (I did complain about that in my review of it).

@voltlog 6 лет назад

I am not a fan of the BM27s or it's auto function but I can kinda see it's utility to allow you to keep your hands free. However I think they could have implement better. Regarding the power consumption you are right. if used constantly in the AUTO mode that relay will drain the battery pretty fast.

Nice items

@voltlog 6 лет назад

thank you!

@matneu27 6 лет назад

A nice toy, but probe cords that connected directly are source of future failure. I assume that the wire will break on the outlet later.

@rubenuspv 6 лет назад

Nice review but you need a voltage reference, one of those cheap AD584L it's good enough, cheers.

@voltlog 6 лет назад

Past few weeks I've been looking at those but also at more expensive nicer options, I haven't decided yet. In terms of specs the AD584L would be good enough but I can't really trust they measurements they write on that label so I would need to take it to a cal lab here which would cost extra. On the other hand if I was to purchase a more expensive reference I could trust the calibration data that I'll get.

@rubenuspv 6 лет назад

I bought 2 of those, one it's the K version on a acrylic box, cost me something around 16-18 usd and included a real voltage reading (a hand-write one) and the second was a L version that was just a PCB board and includes a fake reading (a printed voucher-style one). The L version has a +-5mv precision as maximum but usually it's only +-1mv out, which it's pretty good for
