Review on Efficiently Test Your Antifreeze And Battery Acid With A 3-In-1 Refractometer by Darin Schaffer

Revainrating 5 out of 5

great product, it was calibrated correctly right out of the box

Hight recommend this refractometer, it came correctly calibrated right out of the box, readings are spot on! Thanks for attention.

Pros
  • I use it to measure the concentration of my DowFrost Propylene Glycol on my home heating system
Cons
  • Needs to be calibrated regularly for consistent results
