Portable Hand Auto Battery Hydrometer Refractometer with LED Light

This handheld refractometer with LED illumination is a precision tool engineered for accurate liquid concentration measurement, operating on the principle of light refraction to meet diverse practical and industrial needs.

It boasts a range of user-friendly and durable features: it accurately measures metrics like sugar content (in Brix), alcohol volume, and antifreeze freezing point; its integrated LED illumination module ensures clear readings even in low-light environments (such as cellars or industrial sites); the ergonomic design with a textured grip and compact size (approximately 15–20 cm in length) enables easy portable on-site testing; made of aluminum or high-strength plastic, it resists corrosion and wear for repeated use across conditions; basic measurements require no batteries (only the LED may need power) for reliability in emergencies; and a built-in scale paired with a blue optical lens enhances contrast for intuitive, easy reading.
