Brüder Mannesmann tester batériovej kyseliny 040-T | hustomer pre olovené batérie

Measure the specific gravity of battery electrolyte from 1.10 to 1.30 kg/l with this glass hydrometer, featuring a color-coded scale for instant charge status.

Overview

The Brüder Mannesmann 040-T battery acid tester is a manual hydrometer for checking the charge state and condition of lead-acid batteries. It draws electrolyte into a glass tube via a rubber bulb, where a float with a numerical and color-coded scale indicates the specific gravity. Green means charged, yellow partially discharged, and red indicates the battery needs charging.

What stands out

• Direct reading of specific gravity from 1.10 to 1.30 kg/l
• Color-coded scale: green, yellow, red
• Glass body with rubber suction bulb and nozzle
• Length approximately 250 mm
• For automotive, motorcycle, truck, marine, and industrial lead-acid batteries
