The Jaltest JT3011 is a refractometer: an optical measuring instrument that lets you determine the concentration of a liquid at a glance. Cojali stocks it as the Refractometer JT3011 and categorizes it under measurement and testing. It weighs 243 grams and measures 160 x 40 x 40 mm.
Cojali highlights four applications: glycol concentration (both ethylene and propylene glycol), battery fluid, urea or AdBlue/DEF and the freezing point of coolant. No Jaltest Link, software or license is required; simply hold it up to the light and read the scale.
