Good multimeter for Industrial use at work (Fluke alternatives)

Fungus:
Yep. If there's an arcflash hazard you shouldn't be relying on just the multimeter to save you.

Go look at the photos on the Fluke web site: Everybody's wearing big gloves, face shields, hearing protection... or more.



(Apart from the Fluke 179 guy in the red shirt, but he's a redshirt... :-DD )

Black Phoenix:
He's measuring a 24V control line in the cabinet.

People- don't forget the test leads are also a safety concern and need to be approved i.e. to IEC 61010-031. Tests include wire thickness, high voltage, heat, chemicals (if applicable), tug/yank, drop/bend/impact, probe length etc. all of which are important where your hands are concerned.

But going into a MV motor control cabinet with a LV multimeter is of course a mistake. Ref. Eddie Adams arc-flash fatality. The contactor's coils are LV but one probe to the wrong spot (MV) and it's very bad. Or open control cabinets in the rain, using multimeters then is dangerous. Workplaces need policies around the multimeter usage as a "safe" multimeter can still be used unsafely. Even allowing work alone was not permitted by one of my employers, you could get electrocuted in a substation and nobody would know.

Indeed, but it's highly likely that there will be mains in that cabinet, and quite possibly multiphase mains at that.

3ph UPS bypass switches can be fun; it's easy for a bit of brain fade to make those exceptionally dangerous.

Probably 220V to a PSU for the 24V DC.

Power part of the machine isolated from the control part, with a 220V line from one of the phases, since by the image I don't see any 3 phase equipment in that cabinet.
