RHA-100 ATC

The models have only one unit system: °F. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. And  they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids. The RHA-100ATC has Automatic Temperature Compensation System.

Measuring range: Ethylene Glycol: -84°F-32°F   0-70% VOL Propylene Glycol: -60°F-32°F 0-63% VOL Battery: 1.100-1.400sg Resolution : Ethylene Glycol: 5°F Propylene Glycol: 5°F Battery: 0.01sg   Compensation temperature range: 10°C-30°C

Calibration: zero calibration with water at 20°C ATC = (Automatic Temperature Compensation) for accurate measurements without recalibration after shifts in ambient working temperature.
