Viral Heathrow Scientific 43064 Handheld Refractometer, Ctx-2, Freezing Point °f, Atc, 1/pk Flash Sale: 45% Off [HYOGks6l]

Handheld coolant/antifreeze refractometers measure the freezing point of propylene glycol & ethylene glycol, and the specific gravity of battery acid. They both have automatic temperature compensation (ATC), and come with a 5-year warranty.
These coolant/antifreeze refractometers feature the largest, easiest-to-read scale available with clear, sharp figures, screen shading and incredible contrast. This significantly enhances overall precision, even when several different people use the refractometer. These coolant refractometers also come with a rubber grip on the body, which blocks the transmission of hand heat to eliminate temperature errors.

Large, Sharp Display Scales with high contrast
High-quality optical glass material for consistent, accurate readings
Durable, industrial-grade design with non-roll stand feature to keep unit secure on flat surfaces
Tactical, non-slip Rubber Grip on body to block transmission of hand heat reducing temperature effects
Prism encased in all-metal housing allowing sample and prism to reach temperature equilibrium quickly
