Late last month, I posted about a great sale price on Klein’s MM500 tough and waterproof multimeter. That Klein meter has limited functionality, with its rough and tough case being its primary selling point. It’s not a good choice for one’s first or primary multimeter.
Extech’s EX330 digital multimeter, on the other hand, is an excellent meter, and it’s not very expensive either. I bought one a couple of years ago, as an upgrade to a smaller Extech I had been using, and it has served me well.
My Extech EX330 has played third fiddle ever since I bought my two Agilent/Keysight A34461A benchtop multimeters, Actually, it’s not even third fiddle, as I have a couple of excellent Fluke multimeter samples that I’ve had the pleasure to test and use.
Even so, my EX330 still seems some use, and I cannot bear to part with it. It’ll probably be a part of my test & measurement rotation for years to come.
The EX330 is an autoranging meter that can measure:
- AC and DC voltage up to 600V
- AC and DC current up to 10A
- Temperature with included Type K thermocouple
It also can also test for a couple of other things:
- Diode check
- Non-contact voltage detection
It’s versatile, compact, easy to use, and easy to read. There’s not much more to ask for at this price point.
