The PR53 refractometer is able to hold up to 4 concentration curves in its memory. By default, the unit is delivered with one concentration curve pre-configured at the factory as ordered. Additional concentration curves can be added using the Insight software and a USB adapter. Multiple concentration curves pre-configured at the factory are available as a tailored order.
Do not alter the concentration curve parameters, except if you are changing to another process medium. If you are unsure what to do, contact helpdesk@vaisala.com.
A concentration curve is specific to the given process medium, for example, sucrose or sodium hydroxide. The set of parameters is given by Vaisala. Do not alter the concentration curve parameters, except if you are changing to another process medium.
