Name an inexpensive DMM with True RMS?
« on: June 21, 2019, 12:47:41 pm »
So, what are the trustworthy DMMs down in the "cheap" price range that do a good job of reading TRMS?

Thinking of getting a couple for a dedicated bench function... thanks.

Uni-T 139A and upwards as well as Unit-T 61D and 61E are TRMS.

I think all Brymen multimeters that are not pocket multimeters are TRMS, but they are more expensive.

The Uni-T 61D or 61E may be the best options for bench work since they come with a USB-cable so you can collect data from the multimeters.

ANENG 8008 / 8009.

+1 for Aneng 8008, especially for low voltage DC work.
(I'd exercise caution with AC/high voltage work - no particular reason other than to be cautious)

It used to be possible to find these, some times new in the box for about $20 but that might be difficult now:

After these, maybe Uni-T, and Brymen - just a matter your specific needs and budget.....

Uni-T UT139C (the Amazon equivalent is only $20.00).
https://www.amazon.com/Digital-Multimeter-Synerky-Temperature-Measurement/dp/B077ZQ2Z5S

Well built meters and reasonable input protection. The design is several years old and it is proven to be quite a reliable DMM. 

Up in the reasonably priced range would be the UT-61E with many more features, adds bargraph and remote logging, but its input protection is not great (if that is important to you).

The Anengs have a wide gap in the current range and not great input protection (if these are important for you). I would look at the Mestek DM91A before considering the Anengs.

Some interesting tests are at: https://lygte-info.dk/info/indexDMMReviews%20UK.html

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...
