Battery fluid tester for 12V 24V 6V systems

This electronic refractometer measures battery fluid condition on 12V, 24V and 6V lead-acid types including AGM, EFB and SLI. It gives a direct reading of specific gravity to show state of charge and cell health. The compact body fits in a tool bag for mobile diagnostics. No internal tester batteries are included with the unit.

Suits technicians checking mixed-voltage fleets

Workshops that service cars, trucks and equipment with 12V, 24V and 6V batteries can use one tool across the fleet. It reads AGM, EFB and SLI chemistries without separate testers. Buyers who need a built-in display, integrated load test or included power cells should look at a different instrument.

Tests 12V 24V 6V AGM EFB SLI batteries

The single specification that decides fit is the list of supported voltages and chemistries: 12V, 24V, 6V, AGM, EFB and SLI. If the application uses any other voltage or battery type this tester will not cover it. The device also carries a California Proposition 65 warning for listed chemicals.

Questions about this item

Will the prism or daylight plate need replacement after extended use?

The refractometer uses a solid optical prism with no consumable parts, so no scheduled replacement is required.

What measurement limit is reached first when testing many batteries in succession?

The scale reads specific gravity up to the upper mark; once the fluid reaches that line the instrument cannot show a higher value.

Does the eyepiece or body become hot during continuous testing?

The all-metal body stays at ambient temperature because the tool has no internal power source or heating element.
