Corrosion Resistant Refractometers PR-23-W and PR-23-M
Robust process refractometers are designed to measure concentrations in corrosive og chemically
aggressive liquids as well as ultra pure fine chemicals. Model PR-23-W determines the Refractive Index (R.I.) of the process solution by measuring the critical angle of refraction, which changes with concentration. The critical angle is measured by a digital CCD-element. Suitable for HCl, H2SO4, HF and other corrosive plating solutions. Suitable for ultra-pure fine chemical processes where there must be no contact with metal parts.
