Cell Battery Resistance Tester 4-Term Test Contact Inspection Deviation Deduction 0.1% Accuracy

Tonghui TH2523 Battery Tester, 4-term Test, Contact Inspection, Deviation Deduction, 0.1% Accuracy

1. Safety Features: DC Resistance Meters incorporate safety features to protect the user and the equipment during measurements. These features may include overvoltage protection, current limiting, and insulation monitoring. They help prevent damage to the meter and ensure safe operation in potentially hazardous electrical environments.

2. Portable and Benchtop Models: DC Resistance Meters are available in both portable and benchtop models. Portable meters are compact, lightweight, and battery-operated, suitable for fieldwork and on-site measurements. Benchtop models offer enhanced features and higher measurement capabilities, making them ideal for laboratory settings and dedicated testing environments.

Brief Introduction

As the growth of electronic products, cell phone, home appliances, electric vehicle and bike emerge in an endless stream, all need to work with battery, so the fast inspection on batter will influence the performance of products.

With Tonghui’s experience in impedance test and marketing survey, the new battery tester-TH2523 is successfully launched.It can be competitive with other similar products with its outstanding performance, easy operation and new look.

1kHz constant current source is adopted to eliminate the potential error of thermoelectric force to DUT.

Max.300V(TH2523A) test voltage can meet the demand of high voltage battery

0.1% basic resistance accuracy, the range of 30m-3000 can cover the test demand of large battery pack to button battery,and as well for large type but low resistance lithium battery

The fast test speed can up to 20ms/time

Meet the demand of ACR test for general components.

TH2523 provides multiple interfaces, which is for PC communication and remote control.

Application

Fast test for button battery and battery pack .etc.

For cell phone, home appliances,electric vehicle and bike .etc.

For high voltage battery test

For early battery R&D test

Contact resistance test

Degradation and lifetime-evaluation of battery

UPS on-line test

ESR test of super capactitor
