Vee Gee Scientific CTX-2 Handheld Refractometer, with Antifreeze/Coolant Scales, -50 to 32 degree F Freezing Point

Vee Gee Scientific CTX-2 Handheld Refractometer, with Antifreeze/Coolant Scales, -50 to 32 degree F Freezing Point

Handheld portable refractometer for antifreeze and battery charge level measurement of the freezing point of propylene glycol (-50.0 to 32.0 degrees F), the freezing point of ethylene glycol (-60.0 to 32.0 degrees F), and the specific gravity (SG) of battery acid (1.10 to 1.40) in a 10 to 30 degrees C temperature range Automatic temperature compensation (ATC) for immediate and accurate calibration readings, regardless of ambient temperature Ambient light illuminates the scale; no additional power source is required Durable metal and rubber outer shell with a telescope-shaped, streamlined design (40 x 40 x 150mm), a rubber grip to guard against hand heat for accurate measurements, and a non-roll stand to protect against damage Optical glass prism mounted in all-metal housing for quick temperature equilibrium between sample and prism
