Good multimeter for Industrial use at work (Fluke alternatives)
jonpaul:
Does the OP REALLY need all the logging and graphics and interface of the 287?
The downsides are bulky batteries, slow boot up and fragile large TFT screen, easy to break
For UPS><rotation machines, I would think a simple DVM CAT II or CAT III rated for the V and I max, eg 1000 VAC VDC and 10..20A will suffice at a fraction of the cst.
I sometime find bargains at ebay, LeBonCoin, ham fleas that are old meters new in the box.
CORRECTION: Kline/Milwalkie are just line hot testes and clamp on ammeters. No real DVMs.

All our good one are Fluke, a few old Keithley.
For 50 yrs the analog Simpson 260 has been an industry warhorse as well as the somewhat rarer Triplett 630

1. Starting with the savings: $900
2. The cost of one replacement: $100
3. The cost of getting a replacement ordered. An hour or two of office time: $100
4. The opportunity cost of waiting for the replacement to arrive. A couple days of lower-priority work: $500
5. The opportunity cost of having the technician without the tool at the customer. A few hours of field time: $500
6. The downtime cost at the customer if the technician can't get work done: $500 (Depends greatly on the situation. Could be multiples of this amount.)

All of that applies to Flukes, too. :-//
Flukes aren't more expensive because they're more reliable, they're more expensive because they're yellow and recognizable.

Possibly; but the proposition was that one could by a number of other meters and balance the cost when they fail. The meters are not used in standard conditions, so it's difficult to develop a statistical model of failures. For instance, if an organization had 2000 meters in active use, 1000 each of Fluke and some other meter, and they had certain replacement rates, then one could run some actuarial math and determine the best overall value. This becomes more difficult as the number of units becomes low and the usage conditions are varied.
Therefore, one is limited to a certain amount of reliance on reputation, internet stories, and internet claims - of all kinds.
coromonadalix:
the 287 and 289 are in no ways industrial meters loll
you had this one

Absolutely not in the prices ranges you want

That's why I suggested the OP buy a Brymen and try it out. Minimal cost .. actual experience .. can't beat that
MerlijnD:
About the datalogging on the 287; is it needed? No, some very experienced engineers might use it but very very rarely.
I will have a look at the Brymens; which one should I try out? The 867/869 has the option for two measurements at once I saw in the excel sheet. They are also very cheap. Or the 839?
And maybe try out the rugged brymen for the mechanical people; and the more advanced version for electrical engineers.
We have dedicated amp meters for unit load testing; >3600kva
Is Uni-T even worth looking at?
