This optical refractometer is designed for measuring of following characteristics:

* Scale to determine the battery electrolyte condition
Scale range: 1.10~1.40kg/l
Resolution: 0.01kg/l
Scale range & Result
1.10 to 1.20 kg/l - the battery is discharged (RECHARGE)
1.20 to 1.25 kg/l - the battery is partially discharged (FAIR)
1.25 to 1.40 kg/l - the battery is charged (GOOD)

* Scale G13 - to determine the freezing point of propylene glycol-based antifreezes
This scale is suitable for measuring of freezing point of propylene glycol-based coolants and antifreezes. The scale can be also used for measuring of propylene glycol-based antifreezes in solar thermal collectors circuits or heating pumps and chillers.
Range of scale G13(Propylene Glycol): -50°C~0°C
Resolution: 1°C

* Scale G11/G12 - to determine the freezing point of ethylene glycol-based antifreezes
This scale is designed for measuring of the freezing point ethylene glycol-based coolants and antifreezes like G11 and G12 coolants.
Range of scale G11/G12(Ethylene Glycol): -50~0°C
Resolution: 1°C

* Scale to determine the freezing point of ethanol-based screen washes
Scale range: -40~0°C
Resolution: 5°C

* Scale SRF1 - Scale to determine the freezing point of isopropanol-based screen washes
Scale range: -40~0°C
Resolution: 5°C
