Ensure that the refractometer is not a source of contamination to the product due to damaged or worn product contact surfaces. Misuse (for example, excessive prism wash time or wash pressure) or mishandling may result in metal scratches or roughened surfaces. Such surfaces may not stay clean in processing.
Vaisala offers a 3‑A Sanitary Standard Accepted repair and maintenance package in which all wetted parts, prism, gaskets and dryer are replaced.
| This repair service can be completed only by a 3‑A authorized service center (Vaisala factory or regional headquarters). |
