For Christmas I acquired a UNIT-T UT136B and an Aneng AN8008. Attached is a chart showing some measurements from each along with the same measurements made with a Fluke 179. All tests were done with DC; I'm sure AC works to some extent on both the UNI-T and the Aneng meters but it isn't what I had in mind for the UT136B or the AN8008.
The Fluke is probably about 10 years old. The tests were made using a DMMCheck Plus, a PentaRef, and one other device from voltagestandard.com; these devices are about 4 years old. The tests were made pretty quickly - more chopping with an axe than measuring with a micrometer. Nothing about this is presented as definitive - just some data points.
I initially was curious about the AN8008 but decided to also try the UT136B. The AN8008 might instill slightly more confidence (just a sheer guess) than the UT136B when it comes to measuring but the UT136B might instill slightly more confidence when it comes to durability. I think both will be a-ok if handled with reasonable care. The footprints of both are similar but the UT1368B is almost twice as thick front to back so it feel blockier and stockier (if those are words). The UT136B uses 4 probe inputs vs 3 on the AN8008 so the UT136B requires slightly more replugging. The digits are larger on the AN8008 but both displays are legible. The AN8008 backlight when engaged turns on for 2 minutes (long enough for me); I quit measuring the time on the UT136B after 3 minutes.
The pulse generator on the AN8008 goes in various steps from 50 Hz to 5000 Hz; at 50 Hz the rise time measured 9.5 ms. At 300 Hz the rise time measured 1.4 ms. Not sure what this will do for anyone but maybe it's an entry level function generator with limited functionality for "free" when you buy the DMM. The UT136B is has one slight glitch that might bug someone - the dial pointer doesn't quite line up with some of the markings around the dial; in the middle it's pretty much aligned but on the edges it misses the dots associated with labels. I think it's a printing error and it might just be from a so-so batch; not a show stopper and maybe more than you can expect for the price. If they didn't print the dots and just had the labels (like on the Aneng and the Fluke) you might not notice.
The only tests I made are shown in the chart; both units have lots of functions I haven't tried yet.
Overall what I think the UT136B and the AN8008 would be good for entry level hobby work and/or portable "keep a DMM with you" in your bag or car type uses. Overall, I like both the UT136B and the AN8008.
Merry Christmas, Happy New Year, and Happy Holidays!!!
