The Sealey VS0052 Refractometer is an essential diagnostic tool for automotive technicians and DIY enthusiasts who need to verify the concentration levels of critical vehicle fluids. By measuring the refractive index of light, it provides precise readings for battery acid, screenwash, antifreeze, and AdBlue, ensuring your vehicle's systems operate within manufacturer specifications. While it offers professional-grade accuracy and includes a handy storage case, users should note that the device requires manual calibration with distilled water to maintain consistent performance.

Rotate the eyepiece focus ring until the scale markings appear sharp.
Ensure the prism surface is clean and that the fluid sample has no air bubbles.
Perform a calibration check using distilled water to reset the baseline.
Before your first use, calibrate the unit. Clean the prism with a soft cloth, apply a few drops of distilled water, and adjust the calibration screw until the boundary line aligns with the zero mark on the scale. When handling fluids like battery acid, wear appropriate personal protective equipment (PPE). After each use, wipe the prism thoroughly with a soft, damp cloth to prevent residue buildup, which can cloud future readings. Store the device in the included case away from direct sunlight and extreme temperatures to preserve the accuracy of the prism and internal components.
