Choosing a uni-t multimeter

[EdvinJu]

Hello,
Can you help me. I can't decide which multimeter should I buy ut195m vs ut161e vs ut18b max? I work at substations with relay protection, where the voltage is not higher than 1000 V, and for various household tasks.

None of those. You need CAT 4 rated multimeter, reliable, tested in the EU or in the USA.
Your life is not worth saving a few hundred EUR. Get your employer to buy you a proper meter.
Fluke, Gossen... Maybe Keysight or Hioki. If they don't, just keep in mind that your life is disposable in the mind of your employer.

fluke 87v is a cat 4 certified one up to 600v,      and yes   your company has to buy you the meter

fluke 287 289 ?


the problems is :  many meters drop in Cat xx  beyond 300v ??

I hope this is a troll...

With ut195m you are at 30 euro away from Brymen 867 which is a no-brainer choose ...

287, 289 have same CAT rating as 87V. 1000V is high voltage and is on the limit of these Fluke meters. So I think a high voltage probe would be needed.

There may be a translation or understanding issue here.  Could you explain exactly what a "substation with relay protection" is?

Is even that level of meter necessary? Brymen makes many meters for under 100 Euros.

Very good point on that. Just checking, is it tested by third parties?

Because the 867 is CAT IV 1000V and this isn't.

I couldn't agree more. Get a meter from a reputable brand. At least your family can sue a company with a real office in case you die because of a faulty meter. IMHO Fluke, Gossen, Keysight or Hioki are good, reputable brands. I bought a Keysight DMM specifically to use on mains to make sure I have a meter which is safe. When I bought it, the Keysight DMMs offered more value for money compared to Fluke.

Could you explain exactly what a "substation with relay protection" is?

A mains utility switching and distribution site. "Relay protection" refers to the systems used therein to trip high voltage / high current circuit breakers in the distribution path automatically, in the event of a fault being detected e.g overload, phase to ground short etc.

That is to say, as others have said, it's not a place to be bringing toy instruments to work.

I am not a fun of those web sites that looks like the manufacturer's one and are more expensive than an authorized distributor ...

Anyway Brymen BM2807 CSE is rated 600V only; BM867s is what could satisfy the OP that speak about 1000V.

But really the emplyer should provide what the employee need to carry on the duties.

BM869s is for sure "UL Listed", not sure about BM867s anyway Brymen is a very reputable company.

I know what it means generally, but I'm thinking the OP might mean something else.  Electrical substations usually have a lot more than 1000V in at least part of their wiring.  Here in the US they typically don't have any low voltage at all except for perhaps control systems.

Both meters are on the same platform and certifications. The 869s has some features extra.

I can't tell which country the OP is by looking at the flag. However, I feel with that kind of work the employer should issue the proper meter to the worker.

If you hover your mouse cursor over the flag icon the country or region name shows up.

Don't stop at looking at it ... go over it with the mouse
