Hand-held antifreeze refractometer

Hand-held antifreeze refractometer It is designed for testing for concentration of the battery fluids, antifreeze liquid and cleaning fluids (CF). With the indication of the percentage you may know at which temperature the fluid will be frozen for both propylene glycol(PG) and ethylene glycol(EG). It can also be used for checking the strength of electrolyte solution batteries (BA). RHA-100 and RHA-200 can also measure the concentration of ethylene glycol or propylene glycol in antifreeze liquids.ModelRangeMin.Div.AccuracyRemarkRHA-100EG: -84° F-32° F PG: -60° F-32°F BA: 1.100-1.400sgEG: 5° F PG: 5° F BA: 0.01sgEG: ±5° F PG: ±5° F BA: ±0.01sgATCRHA-200EG: -60°C-0°C PG: -50°C-0°C BA: 1.100-1.400sgEG: 5°C PG: 5°C BA: 0.01sgEG: ±5°C PG: ±5°C BA: ±0.01sgATCRHA-300EG: -60°F-32°F PG: -50°F-32°F BA: 1.15-1.30sgEG: 10°F PG: 10°F BA: 0.01sgEG: ±10°F PG: ±10°F BA: ±0.01sgATCRHA-503EG: -50°C-0°C PG: -50°C-0°CCF: -40°C-0°C BA: 1.100-1.400sgEG: 5°C PG: 5°CCF: 5°C BA: 0.01sgEG: ±5°C PG: ±5°CCF: ±5°C BA: ±0.01sgATC
