Anti-freeze Coolant Freezing Point Tester User Manual

1. Principle:

Antifreeze Freezing Point Tester is a precision optical instrument used to measure the freezing point of antifreeze. Its basic principle is to measure the refractive index of the solution using the total reflection critical angle method, thereby calibrating the concentration and performance of the measured liquid.

Due to its reliable principles, precision that meets actual needs, and advantages such as small size, light weight, attractive design, and convenience of use, it is widely applied in the automotive industry.

Section Two: Basic Parameters:

Field of view explanation:

Middle scale: (ETHYLENE GLYCOL) Antifreeze with ethylene glycol.

Propylene Glycol (PROPYLENE GLYCOL) Antifreeze Ice Point.

Left scale: (BATTERY FLUID) Battery Fluid Specific Gravity.

1.15~1.20 needs charging

1.20~1.25 battery capacity is sufficient

1.25~1.30 Battery is fully charged

Right scale: Glass cleaner ice point

Attachment: Instruction Manual, Screwdriver, Straw, Velour Cloth.

Attention:

• Do not place the optical system in an environment with relative humidity greater than 85% for a long time to avoid any adverse effects on the optical system.
• Do not put liquid or water into the adjustment knob and eyepiece, or it may damage the internal components.

• Do not drop or collide, to avoid damaging the instrument's precision.

Note: This instrument can measure ethylene glycol and propylene glycol, but it cannot measure methanol!

This test instrument can measure:

* Specific Gravity of Electrolyte

Measure the type of antifreeze for ethylene glycol

* Propylene Glycol-based Antifreeze

* Testing the freezing point of windshield washer fluid

This instrument is a temperature compensation type with an internal temperature compensation device.

Guarantee accurate measurement within an ambient temperature range of 10°C to 30°C.
