A refractometer is an easy to use laboratory or field device to measure the concentration of the Hydrophilic Remover (ZR-10B) in water and is required to meet Pratt and Whitney and GE concentration specifications for hydrophilic removers.
A chart for converting refractive index to percent concentration of ZR-10B is available on the Magnaflux website.
Specifications Compliance: Meets Pratt and Whitney and GE specifications.
