Extech 380947 400A True RMS AC/DC Mini Clamp Meter

5.0

I really like this mini clamp meter from Extech. With its 23 mm jaw opening, I can use it in crowded spaces where other clamp meters won't fit. This meter is easy to use and the display is large and clear and easy to read. I needed a meter with high resolution on low current measurements, and a meter that measures frequency, and this meter does that up to 10 kHz. I also like the data hold and min/max features. Thank you, Extech!

Product is very easy to use as well as the szie allows you easy access to more confined spaces. Would recommend this product to anyone that has a need for a clamp meter in tight locations.
