The ACT 33 is an amazing new battery tester that can simultaneously measure battery voltage, internal resistance, temperature, current and Ah capacity - without having to disconnect the battery in order to test. It will test a wide range of Alkaline, Ni-Cd, Li-Ion, Ni-MH and SLA batteries with voltages from 1.2V to 24V and capacities up to 1200Ah. Recorded measurements can be downloaded to a PC for analysis or optionally printed out.

The ACT 33 is a new, innovative battery tester that can simultaneously measure battery voltage, internal resistance, temperature, current and Ah capacity without having to disconnect the battery in order to test. Such ‘True-Life-On-Line’ testing is an ideal solution for when a complete shut down is not an option.

The ACT 33 includes a built-in comparator and datalogging function and is capable of a load test analysis. The ACT 3092CP current clamp provided enables simultaneous measurement of charge/discharge current, battery voltage, internal resistance and Ah capacity. With the RS-232 interface PC software, the user is able download recorded measurements on to a PC for analysis. An optional ACT 300XP Thermal Printer is also available.
