The BT-120 tester allows you to accurately test a wide range of battery parameters to ensure optimal battery performance. Designed for both professionals and home users. This reliable tool provides accurate measurements and precise information about the condition of the battery. Benefits include monitoring the performance of batteries to avoid unpleasant surprises, making informed decisions about the continued use of batteries or their replacement, ensuring reliable power supply in a wide range of applications and identifying potential problems by measuring the ripple voltage. 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. It also 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. The tester allows you to measure the internal impedance, which assesses the condition of the battery and assists in making informed decisions about its further use. It can also measure the ripple voltage down to 5 V to identify potential problems, such as cell damage or improper charging. This is crucial to maintaining battery performance. Suitable for use in the automotive, electrical, renewable energy and telecommunications industries.
