Review on 🔧 Extech 381676A Pen MultiMeter with Built-in NCV: Fully Loaded Pen-style Meter with 9 Functions, Auto/Manual Ranging & Large 2000 Count LCD Display by Cody Howard

Excellent device. It's ideal if you don't want or need to connect a $5,000-$10,000 Hewlett-Packard digital microvoltmeter with a data sampling rate of 500,000 samples per second. Remember to always use Energizer lithium batteries in this device. I have never seen batteries of this brand leak and cause damage. I NEVER use Duracell. This slightly different model is beautiful.
