What manufacturer makes what brands of multimeters? For example I believe that CEM makes Extech multimeters. I think Craftsman and Southwire were also made by CEM.

Too many to list. Easier to know who makes or design their own meters.

Obviously Fluke and Keysight. I can't think of anyone else now.

APPA is the manufacturer of Ideal, Greenlee, Iso-Tech, Jensen, Westward, Benning, some Tektronix and Megger meters, plus other brands.
Some other OEM manufacturers of other brands are Brymen, Uni-T, and Mastech.
In the past there were even rebrands of European meters: some ITT Metrix units were rebranded by BK Precision!

retiredcaps · « **Reply #3 on:** January 12, 2018, 07:29:30 am »

Just thought of a couple more who make their own meter and don't allow rebranding. Gossen and some Hioki high end meters.

I believe Greenlee is made/rebadged by Brymen.

Actually Gossen do/have rebranded their meters as Dranetz, Siemens, Avometer, Unigor, I've even seen a ABB metrawatt on the bay of evil.
Someone had an Megger branded Gossen 28S for sale here a while ago
https://www.eevblog.com/forum/buysellwanted/gossen-metrawatt-metrahit-28s-(avometer-oem-clone)/
Gossens Metraclip 61 leakage current clamp is a Megger DCM300E

I think Hioki even rebadged someone elses at one stage as their own.

Fluke's leakage current clamps are actually Yokogawa's

Everyone rebrands the AEMC SL261/Chauvin Arnoux E3N clamps and a lot of their other ones.

Greenlee used to exclusively rebrand APPA, in the past 5-10 years most of their higher end stuff is now all Brymen. They still have a few APPA models but these are becoming fewer and fewer.

The way I understand it, at least in the past, APPA was making multimeters for Tektronix but they were a Tektronix design.

As the above posts indicate, it's especially complicated as often the brand will encompass more than one company's products rebadged to the brand, and sometimes alongside first party produced products. You've almost got to approach it on a product by product basis, as one brand name may have three different OEMs producing its product line and different ones in past product generations.

Gossen/Metrawatt and Sanwa for sure. I'd also suggest Beha-Amprobe (Danaher Corporation as Fluke), Hioki, Kyoritsu, Der EE, Tonghui, Yokogawa all do their own. There might be co-development across some brands, esp. from Danaher-brands like Fluke, Tek & Amprobe, but overall those companies should have their own development.

Brymen makes their own meters under their own brand. They also design and make the MM series of Extech meters, the AM-250, 270, 140, 160, and PM pocket models for Amprobe, Some of the Brymen models are re-branded by Greenlee and some other lesser known brands. Many Amprobe clamp meters are re-branded Brymens.

Fluke and Tektonix are part of "Fortive" (spinoff of Danaher mid 2016).

I'm not so sure about Sanwa, they use Brymen ICs and apparently the same data logging cable. Maybe someone has more info. Amprobe rebrands stuff developed by Uni-t(to a better standard) and Brymen I think. Don't know about the Meterman stuff, did they buy that company or is it their own brand? Kyoritsu has same/similar meters to Yokogawa.

Gossen Metrawatt have clones of their MetraHit 28s meters under AvoMeter M3045S, Siemens B1105 and Drantech Ultra M230H, ST Gamma 20, Unigor 380 or 390, Rishab RishMulti 20 (but have less functions)

I had the AvoMeter clone, and a Metrahit 28s the input protection is slightly different in parts, it loose the cat IV specs ... but same quality fuses.

Slow in display speed, but incredible features not found on recent meters, ditched my flukes, they lost me with the 83 series 5 models (ac modes by default, erk could not stand it).

Now added an Gossen 29s to my collection.

The first Agilent handheld DMM's where relabeld ~~Records~~ Escort's (if I remember the name well) until Agilent bought the company

lem_ix · « **Reply #16 on:** January 13, 2018, 08:28:11 pm »

Think it was Escort actually.

AvoMeter M3045 - absolutely no google hits for me?

The last digital AVO I remember after some research is the AVO DA116. I had one of these AVO meters back in 1989/90 and it was insane compared to handheld DMMs like a Fluke. However I have since learned it was actually of 1977 vintage and used the same hand wound and calibrated resistors of the AVO 8 which does excuse its similar massive bulk.

Elektrotanya has the manual with schematics

I zapped mine on an old Philips G8 HT supply that went to the diode "tripler" to produce EHT. An AVO 8 could cope with the HT no problem. That sprung cutout could deal with anything

ModemHead · « **Reply #18 on:** January 13, 2018, 08:42:29 pm »

Speaking of Agilent, here's an interesting re-brand for you. It's a Fluke 19 with "Agilent 977A" on the front.

Yeah, right. But nothing really changed (for Fluke or Tek), because they span off all tech related parts.. ^^
Fortive has ~80% institutional owners, it's just another big mixed tech company. Doesn't really matter if the owner is called Danaher or Fortive or "Fantasy Name Inc".

Very interesting. Megger own the AVO brand. Perhaps this is some prototype marketing of the old AVO label?

I've tried Google, Bing and duckduckgo and can't find the M3045S for sale or images anywhere other than ebay sale.

There are plenty of "part number aggregation" websites that just waste everyones time with shit results and are internet cancer that google should deal with instead of diversity bollocks.

Thank you Zeitkind, I was particularly amused at this:

AVOwins-DMM Software
• Runs under MS Windows 3.0+, 95 & NT

That seriously dates it for sure (1995!) - Megger tried to use all that was left of AVO (their brand) and it appears they failed.

oh oh, found another Gossen 28s clone, from Dranetz a DranTech ULTRA ...
