Good multimeter for Industrial use at work (Fluke alternatives)

--- Quote from: MerlijnD on December 22, 2022, 06:59:10 pm ---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.

And maybe try out the rugged brymen for the mechanical people; and the more advanced version for electrical engineers.

The 869s is Brymen's top model. It's one of the best meters available and has CAT IV 1000V safety rating (higher than any Fluke) and has dual display, eg. voltage/frequency simultaneously. The screen is a bit too exposed to throw it in a toolbox though.

The 859s is their top "industrial" meter.

Both models have cheaper versions without temperature and less TRMS bandwidth.

Start with the 869s - it's obviously bigger than a Fluke and has dual display so it will be easier to "sell" to engineers. After that you can get some of the less flashy 857s for situations where a simpler meter that can take more abuse is indicated.

Absolutely not.

This is also true. Brymen have earned their reputation on EEVBLOG but the rest of the world doesn't know much about them. The engineers might feel you're trying to pinch pennies at their expense if they've got used to yellow meters and you give them something that isn't yellow.

Alternatives to Fluke regarding safety and reliability? Aaaand a calibration structure behind them? Gossen Metrawatt comes to mind, but they are usually more expensive than Fluke- or maybe one of the newer models has some useful features to it than the existing Fluke meters. Also Hioki looks nice, but I have no first-hand experience with them.

daisizhou:
Look at this one, the latest may be 27.Note that 27 is not equal to 27/FM.
I think 27/FM is the only one if you consider durability.Because the latest 27ii or 28ii are not as good as 27/FM, you can check the 27/FM shell or dial switch.Shock resistance is key

Dam, the quoting system has gone down again, so I'll have to cut and copy and hope that you all can catch my drift.

        2. Let's say the cost of a Fluke is $1000, and the cost of an alternative is $100. It only takes one failure event to lose this savings.

    You might want to expand on your math.  If one casts $1000 and the other cost $100, then the cheaper one only needs to last 1/10 the time before the saving are lost.  Do you have another consideration you are factoring in that we don't know about?

        US Kline

    Do Kline actually make any of their meters?

    To the OP:  Brymen's top level meters generally meet all the same specs as Fluke and are also independently certified by the same people (UL)  to meet those specs.  I would suggest getting a couple and trying them out.  See for yourself how they stand up.


We can consider the total costs of a failure in the field. Feel free to propose other numbers.
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.)
7. The cost of reputation, etc.: ?

The point being that the line-item cost difference is easily noticed and accounted for, while difficult to identify costs don't enter into the accounting. For instance, is it trivially easy to purchase the new meter, or does a purchase requisition have to get filled out, get approval, go to Purchasing, wait for delivery, etc. That differential is difficult to measure, but it shows up as an indistinct "tax" or drag on efficiency and productivity.


Surely then it makes perfect sense with the high costs attached to meter failure and the lower purchase price of the excellent Brymen 867/869 meters that you could comfortably afford to order in a few extra meters to allow for such unlikely events? That way, if and when you do happen to get a failure, issue another one from stock and start the process of ordering a replacement so that will always have a small float of meters to hand for emergency use and still be way under the cost of getting new Fluke meters.  I have both Flukes and Brymen meters but only the Brymen has the CAT IV, 1,000V rating, and that is the meter I use for almost all of my measurements, it also has dual display and the barograph and can be retrofitted with data logging feature for those that really need it.
 

nightfire:
One thing to add: In which environment are those UPS used? If they feed into some main distribution cabinet of a sufficient size and short circuit potential, you are easily in a CAT IV zone- and then there is a limited choice of manufacturers I would trust. And then, including yearly cal and needed turnaround times, Fluke sometimes offers good longterm value, all costs added over a longer time.
