You forgot to mention the price.

OK Bob and here the Price is ? and the contestant that is nearest

79.95 at multimeter depot these are new and just came out and the winner is Me! I bought 1
I found it on ebay but you can still get it at multimeter depot on the internet

for a multi-purpose meter it specs very well.
I am so glad the designer saw fit to omit transistor hFE. Forcing one to use a proper test.

Protek 6300 - 3 3/4 Digit DMM with Luminance, Sound level and Relative Humidity

also very similar or exactly the same
http://www.protektest.com/Prodinfo.asp?prodid=6300
Mouser.com carries it MSRP $69 USD ie can be had for less
Harbor freight "had" a rebadged one a while back for around $39.

I'm curious how sound level works?

Does it have a built-in microphone? Do you add your own external mic?

I also notice that the sound level frequency response is only 100hz to 8khz. That might be good for general sound levels, but not for detailed testing.

Is that limited by the internal mic and can it be improved by adding an extremal mic?

Still, it's a sweet meter for a very modest price.

[mcmahon48]

it has a microphone built into the bottom

There is a microphone, Light meter, temptature/ humidity I will bet some one around here will figure a way to tweek it to take a microphone sooner or later. That also bring up an interesting subject who can tell us how to make a califrated spl measuring microphone up 40khz that will work with it

 

[soongsc]

Hope someone does come up with a cheap mic up to 40KHz.

 

[Pano]

That's a lot of meter for the price!

Nice to see it has the milliamp ranges for AC, so many of the low end or all-in-one meters don't. Funny that it does lux, humidity and SPL. Never seen that combined before. =)

 

[jol50]

I could use a spl meter, but yeah I would want to test response 20-20K.

What a piece of junk- it doesn't have GPS, you can't take a picture with it, no calculator and not even a phone!

 

[mcmahon48]

Well at least go to the correct forum

yeah you are right in that regard but post it in the right forum LOL

 

[slam]

Circuit Specialists has a very similar meter for around $43. On top of that they throw in a (even cheaper) meter for free if your order is over $50 and you ask for it.

5 in 1 meter

While very cheap, not super accurate, and not auto ranging, the free meter is somewhat useful as it measures hFE and temp, and has 4V AC range with 1 mV resolution.

I have a couple of those cheap meters, they are great for watching the voltage or idle amps when testing an amp. (car amp) Harbor is hard to beat for cheap stuff, all from China I am sure.
