Testing Coolant Mixture After Service
Why should coolant concentration be tested after servicing a cooling system?
Answer
Created on: Mar 4, 2026, 9:16 PM by Admin
Testing coolant concentration verifies that the antifreeze mixture provides the correct freeze protection and corrosion protection for the system. Incorrect mixture ratios can lead to reduced heat transfer efficiency or insufficient freeze protection.

Determining Freeze Point of Glycol Coolant
How can the freeze point of glycol coolant be measured?
Answer
Created on: Mar 4, 2026, 9:16 PM by Admin
The freeze point of a glycol solution can be determined by measuring its refractive index and converting that value into a freeze point temperature using calibrated scales. The PA203X refractometer performs this calculation automatically and displays the freeze point in degrees Celsius.

Refractometer vs Hydrometer for Antifreeze Testing
Why use a refractometer instead of a hydrometer to test coolant?
Answer
Created on: Mar 4, 2026, 9:17 PM by Admin
A refractometer measures optical properties of the fluid and provides more precise digital readings. Hydrometers rely on density measurements and floating indicators, which can be affected by contamination, additives, or temperature. Digital refractometers typically deliver faster and more repeatable results.
