Description
The 5-in-1 Hand Refractometer is a versatile diagnostic tool engineered to test and monitor five critical automotive and industrial fluids: battery electrolyte (SG), ethylene glycol, propylene glycol, urea (DEF), and windshield washer fluid antifreeze. Designed for fast and accurate field testing, this refractometer is an essential device for mechanics, fleet managers, maintenance technicians, and industrial operators.
Built with a durable aluminum body and equipped with Automatic Temperature Compensation (ATC), it ensures consistent, reliable readings across a range of environmental conditions—ideal for workshops, garages, and on-site maintenance.
