Tooltop IR500 / IR502 Battery Internal Resistance Tester for Lead-Acid / Nickel-cadmium / Lithium Battery

Tooltop IR500 / IR502 Battery Internal Resistance Tester for Lead-Acid /Nickel-cadmium / Lithium Battery

Features:

• This battery internal resistance tester adopts 1KHz AC low resistance measurement technology and Kelvin four-wire detection, effectively eliminating the influence of line and contact resistance, realizing high-precise internal resistance and voltage detection of various types of small batteries, such as lead-acid batteries, lithium batteries, nickel-cadmium batteries, alkaline batteries, etc

• It is especially suitable for testing and maintenance of automotive batteries (electric vehicles, motorcycles, traditional cars, new energy vehicles, and electric vehicles)

• With a self-calibration function to ensure continuous accuracy, users can calibrate themselves according to their needs, are equipped with a filtering function and double alarm prompts, based on the preset upper and lower limits to determine whether the battery's internal resistance is qualified automatically, and through the nice, qualified, poor three-level prompts to display the test results visually

• With the automatic resistance/voltage switching function, the measurement ranges from 0.000mΩ to 500.0Ω resistance and 0.000V to ±120V voltage.

• The 3.2-inch display can simultaneously display the internal resistance and voltage values. The internal resistance measurement supports six automatic switches to simplify the operation process

• The backlit display and LED flashlight function ensure it can operate in a dim environment

• The housing is made of ABS material and is fully wrapped with a TPR (thermoplastic rubber) design for a comfortable grip, providing shock and drop-resistant features, ensuring that the instrument can still work stably in harsh environments

• Built-in a 1200mAh high-capacity lithium battery, with a short charging time of 2 hours, it can continue to work for about 8 hours, effectively protecting long uninterrupted on-site testing needs

• With its professional and accurate test performance, humanized design concept, nice durability, and long endurance, this battery internal resistance tester is a useful partner for battery maintenance and troubleshooting
