content: Hello,I want to buy used Brymen BM235 or BM257 without "s" at a reasonable price. I prefer people from EU, because of the shipping costs. I suppose if someone throw me a good offer from another part of the world I won't complain. :-)Thank you.edit: BM235 was added.

content: if you're interested I have a 257s like new90 € plus shipping, shipping from Spain Post = (Correos) (it's easier for me)I think the shipping to Europe is about 20 €

content: Unfortunately, I expect owners of the original BM257 won't be parting with them anytime soon (S variant changed the input protections slightly to handle higher transients per an update to CAT ratings). They're just too good and too new right now. If they've been around a couple of decades, then it would be a different story.So you'd either have to buy a new one from TME (need to save up a bit?), or settle for something else that fits your existing budget. Best to check out the latest "what DMM to get" threads to get an idea of starting points.For example, theUni-T UT139Chas decent protections (safe for probing mains), lots of features, and can be had for ~$50USD shipped off ofBanggood, ... (under $40 shipped to EU nations oneBay). Lots of info on this one here in the forum. Decent meter to start with IMHO, and doesn't cost a mint.BTW, if you go into your user profile and set your country, the flag will be displayed beneath your userID of each post. Makes it drastically easier for members to post relevant links.Best of luck.

content: Quote from: nanofrog on July 04, 2018, 12:35:35 pmHello nanofrog,Thanks for your message. TME sell BM257s for 120€ and as far as I know the warranty is 1 year, not 3 years. I already own UT61E and I want something with better protection and a little bit more precision.My hope is for someone who upgrade their BM257 for something better. I'm searching for the model without 's', because it should be cheaper and I have spare HRC fuse that I can use in a case of emergency. :-)I suppose you are right about the owners, but I hope to save €20-40 bucks from new and not to pay the full price for a second hand.Regards,edit: TME warranty is 1 year!

content: Quote from: sonny on July 04, 2018, 01:21:19 pmBrymen only offers a 1yr warranty. Longer might be possible as a rebrand or per national/EU regs. that govern warranty.I wouldn't sweat the warranty term though, as they're really well made IME (I've a BM857a made back in the late '90's still going strong). Others' comments echo this as well.In regard to getting a used BM257, I neglected to mention a critical fact. Which is most of use tend to add to our collections rather than swap it out (other gear too), but especially when it comes to DMM's. And there's a valid reason for this; it's not uncommon to need simultaneous measurements which usually requires multiple meters (i.e. simultaneous current and voltage measurements).In regard to Uni-T, their meters are all over the place in terms of protections and build quality, so you have to do your homework.For example, the U61E is a 22,000 count meter that doesn't have good protections and is also known to drift rather notably (it's covered here in the forum if you search). In contrast, the UT139C is a 6,000 count meter (as is the BM257, which is why I mentioned the UT139C). But unlike the UT61E however, it has decent input protections suitable for mains use and no reports of them drifting out of spec.In regard to counts, accuracy, and resolution, you might want to take a look at the following video:

content: Quote from: nanofrog on July 04, 2018, 02:49:28 pmAs far as I know there are two main revisions of the pcb for UT61E. The old ones used a very low quality pot in VR1 (no brand) which is the main reason for drifting in the voltage. And the new ones come with JML branded pot, which gives better stability. I know JML is not quite an improvement, but it's a way better than the old crappy one. And as I see the complains for drifting are mostly from the old revision.As for the UT139C I completely agree. It hasn't any pots inside and the calibration data is stored in EEPROM. So no vibration could cause loose of the calibration like with the pots.

content: Quote from: sonny on July 04, 2018, 05:53:49 pmRight -- and I can confirm that the case, and specifically the test leads, are very nice quality. The test leads also come with screw-on banana plugs for the tips. When I ordered my meter, a year ago or so, Welectron did not have the two separate ordering options, and always sold the meter with the accessories. I am glad they made that decision for me, but would indeed recommend ordering the set including the accessories.Disclaimer: Happy customer, but no other affiliation.

content: Quote from: sonny on July 04, 2018, 07:56:02 pmJust looked up the invoice - my BM257s was 109 Euro with the accessories, in May 2017. Only the silicone leads were included. I believe Welectron get the meters configured complete with the case and better leads directly from Brymen; they are an official distributor.

content: Same with me. Bought some days ago (130€ on Amazon Marketplace). It came with one set of silicon leads, banana plugs and the soft bag. I know it's my first post and it sounds strange but i'm not affiliated or anything.

content: Quote from: sonny on July 07, 2018, 03:46:26 pmOf course it is BM257S in Welectron. 257 (without S) is older revision... You can't get it anymore, unless it old stock..Ebastler said he got his for 109 last year.. I just gave current data.Regards,

content: Quote from: sonny on July 07, 2018, 02:14:32 pmYup! BM257s. I was actually surprised when it arrived because on Amazon there wasn't any mention about the additional stuff it came with, so i just assumed it costed that much. The blue/yellow temp probe is not included in the standard set? I got that one too.
