Vaisala K-PATENTS Sanitary Refractometer PR-23-A enables accurate in-line Brix and concentration measurements and control in dairy, liquid food and beverage applications as well as in pharmaceutical and biotechnology processes. The 3-A sanitary certified refractometers are ideal for hygienic processing, where in-line monitoring and control can help to improve product quality and reduce costs.
The measurement range of the refractometer covers the full range of 0-100 Brix. The typical accuracy is ± 0.1 Brix, and the measurement is automatically temperature compensated. Low and high concentration alarms can be configured. Because of the digital sensing technology, even large amounts of suspended solids, bubbles or color changes do not affect the measurement or the accuracy.
Each sensor is provided with a calibration certificate comparing a set of standard liquids to the actual sensor output. The calibration and accuracy can be verified on-site with the certified Refractive Index liquids and Vaisala's documented procedure.
The 3-A symbol guarantees that the sanitary refractometer PR-43-A conforms to 3-A Sanitary standard number 46-04 for refractometers and energy absorbing optical sensors for fluid products equipment for sensing concentration, and it has passed the independent third party verification inspection for 3-A symbol authorization.
The measurement is accurate across the full concentration range of 0-100 Brix: R.I. nD ±0.0002 corresponds typically to ±0.1 Brix or % by weight.
The measurement is not affected by bubbles, particles, color or vibration. The system withstands CIP and SIP cleaning.
There are no moving parts within the refractometer that would require regular maintenance.
Fully digital instrument. Drift-free calibration. No need for re-calibration and mechanical adjustments.
