The Midtronics CTM-300 Celltron Module Test Meter is a handheld conductance-based battery analyzer for testing individual cells or modules within lead-acid battery systems. It uses proprietary conductance testing to assess battery health and identify weak or failing components without discharging the battery. Results are displayed in Siemens (G), Mhos, or as a percentage of reference conductance value.
