    Sonel BT-120 tester is a measuring tool that allows you to accurately test a wide range of battery parameters to ensure optimal battery performance. Designed for both professionals and home users, BT-120 tester is a vital support for keeping batteries in excellent condition.

    Sonel BT-120 tester is a reliable tool that provides accurate measurements and precise information about the condition of the battery. It allows to:

    • monitor the performance of batteries and avoid unpleasant surprises related to their improper operation,
    • make informed decisions about the continued use of batteries or their replacement, based on internal impedance measurements,
    • ensure reliable power supply in a wide range of applications, from vehicles to emergency power systems,
    • identify potential problems, such as improper charging or cell damage, by measuring the ripple voltage.

    With Sonel BT-120 tester, you can rest assured that your batteries are operating at full capacity, delivering power when you need it. Find optimal power solutions for your devices with a tester that offers reliable measurements and precise information.

    AC/DC current measurements

    The tester can accurately measure AC and DC current up to 400 A. This is crucial to assess the battery's ability to deliver power and identify any problems with current flow.

    AC/DC voltage measurements

    BT-120 allows you to measure both AC and DC voltage, up to 500 volts. This is important for monitoring voltage stability and matching battery voltage to the requirements of powered devices.

    Internal impedance measurement

    Internal impedance is an indicator of the battery's condition. The tester allows you to measure this value, which allows you to assess the condition of the battery and make informed decisions about its further use.

    Ripple voltage measurement

    Measuring the ripple voltage down to 5 V identifies potential problems, such as cell damage or improper charging. This is crucial to maintaining battery performance.

    Industry versatility

    BT-120 is used in a wide range of industries, from automotive and electrical to renewable energy and telecommunications. It's a tool for professionals concerned about power reliability and efficiency.
