Battery Resistance Tester

Overview

The MT247 is a general rechargeable battery internal resistance tester, Abbreviation: battery internal resistance tester. The MT247 is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead storage batteries, GEL batteries and lithium batteries to determine the health of the battery. It can also be used as a meter to measure the ESR parameters of electrolytic capacitors (for reference only). The meter uses AC 4-terminal test method to measure the internal resistance of the battery and can measure the correct measurement value without being affected by the contact resistance between the test wire, terminal and battery electrode. It also has the functions for data storage, data access, alarm and automatic shutdown. The high grade of the MT247 is a reliable tester with a stable performance has a wide measuring range, high resolution and accuracy, with strong anti-interference ability. The compactness of the meter ensures it is easy to carry to any site, and is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance and other scenarios. Stored data can be transferred to a PC using an optical USB and software supplied.

Gorgeous shelf

Gorgeous shelf! I know it’s not real wood but you can’t tell the difference and the price is right! Pipes are beautiful too! My dad put this up and had a little trouble aligning it up with the holes so make sure you have um right before you start drilling them.

Not REAL wood - particle board with veneer - but still beautiful.
Color: 1set, Size: 24inch, Color: 1set, Size: 24inch
Came on time, easy to assemble, relatively easy to install. Metal rods are actually metal, which is nice. Flanges are good quality, very nice rustic look. Shelves are less wonderful. They are definitely not real wood at all. They are cheap particle board with veneer. I would not have purchased had I read more reviews, BUT it is still beautiful, sturdy and does the trick. We can always cut our own shelves if we should so choose and re-use the very nice hardware. 4/5 for misrepresenting as real wood, but 5/5 for functionality and aesthetic.
