The Jaltest JT3011 is a refractometer: an optical measuring instrument that allows you to determine the concentration of a fluid at a glance. Cojali stocks it under Refractometer JT3011 and lists it in the measurement and testing category. It weighs 243 grams and measures 160 x 40 x 40 mm.
Cojali identifies 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 licence is required; simply hold it up to the light and read the scale.
