Whether your battery is

Lead-acid battery,

Ternary lithium battery

Lithium iron phosphate battery

or other types of batteries,

as long as the battery voltage is

within the measurement range, they are all applicable.

Automatically identify and monitor the current in both charging and discharging directions.

*When charging and discharging occur simultaneously, the displayed value is the difference between the charging current and the discharging current.

Built-in buzzer, intelligent monitoring

—ensuring your safety.

Once the preset low capacity or low voltage alarm is triggered, the buzzer will sound immediately, and a popup reminder will appear, keeping you informed of the device status and preventing accidents. Choose us for safety at your fingertips!

PURE COPPER

SCREW SHUNT

Powerful Mobile App

More flexible and convenient to use

1-All-New Design

>To provide a superior user experience, we have completely redesigned the coulometer's app interface.

>This app interface is not only aesthetically pleasing but also rich in features.

>More importantly, we have added dynamic charging effects, allowing you to visually understand the battery's charging and discharging status, adding a lively touch to the app.

2-Comprehensive Display

>Through the app, you can view key data such as battery voltage,

charge/discharge current, power, remaining capacity, and estimated time.

>This data will help you better understand the battery's working condition, enabling you to make informed decisions.

3-Comprehensive Settings

>Not only can you view data, but you can also fully configure the

coulometer through the app.

>From simple interface style adjustments to complex data analysis and parameter settings, the app offers a one-stop solution.

4-Intelligent Platform

>Our newly developed Junce Home intelligent instrument platform is a fully integrated solution, dedicated to providing stable and reliable intelligent instrument services to users worldwide.

>This platform, centered around the KM series coulometer and JUNCTEK products, combined with mobile app control, offers an unprecedented intelligent experience.

The built-in storage chip ensures that parameters are not lost during power outages. When power is restored, the device continues to operate according to the pre-outage settings.

Considering outdoor usage, we have added a screen inversion function. In bright light or sunlight, the screen can be manually adjusted to a white background to ensure the displayed content is clearly visible.
