The Major Tech MT247 is a rechargeable battery internal resistance tester. Simultaneously measuring the 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 to measure the ESR parameters of electrolytic capacitors (for reference only). The meter is not affected by the contact resistance between the test wire, terminal and battery electrode. It also has functions for data storage, data access, alarm and automatic shutdown.
The Major Tech MT247 is a reliable tester with a stable performance. It has a wide measuring range, high resolution and accuracy. 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.
