Looking for Benchtop Multimeter - Cheap but good enough
<< < (3/5) > >>
Fungus:
Is the requirement for "good enough":

a) "Meter for basic measurements that can be left on all day"
or
b) "Meter with traceable calibration at a reasonable price"

If it's (a) then there's loads of cheap options. If it's (b) then the calibrations can easily swap the cost of the meter over time.

Hi,

Thanks for all the answers so far.
For the daily purposes we don´t need a 5.5 digits or above meter (we got 2 keysight 5.5).
When adjustments of the circuits are needed, we didn´t this over 3 digits after the comma, mostly 2.
The meter must be calibrated every year as we are under ISO9001.
It should have mV range.
Low cost china "we don´t know it, we only sell it" brands are out of the race.

Martin

Look past that to see the different spec between the west and east models that are now proven to be the same HW.
3045X is the oddball in the range, some of its measurement ranges have been SW changed whereas the Chinese 3055X-E measurement ranges match the 3055 and 3065X we see in the west.

Look, SDM3045X have been more popular here than I expected and buyers seem to be satisfied with them and AFAIK use them as you intend, precise measurements are not required but only good enough...service bench type use.

Does the calibration needs to be done with official certificates (=external lab), or, given a sufficient number of devices could be done inhouse to check against a known good 5.5 multimeter?

In this case, I would make the decision dependant upon the recurring calibration costs from the calibration lab they should quote- maybe a Fluke or Agilent/Keysight device will come in the long run (as they can operated for 10 years with no big problems) cheaper.
In that case, ask your cal lab for some pricing and then choose the one with the cheapest cost that will follow...
Maybe get some used stuff like HP 34401 or old Fluke 45, if they are sufficiently cheap to calibrate...

If you're "ISO9001" then there has to be a full paper trail in case of audit.
