Do you own a Vaisala K-PATENTS Process Refractometer PR-23, PR-33, or PR-43, or the Vaisala Polaris PR53 product?

Calibration, prism replacement, and repair services for these product platforms are now available to purchase through Vaisala’s online store, operating around the clock. Ordering online significantly speeds up our already rapid ordering process, eliminating manual steps such as completing an RMA form or awaiting order processing and associated RMA-linked order numbers.

Avoid the unexpected with Vaisala’s Care agreement

Vaisala’s process refractometers are durable and made to last, in some applications even for decades. Yet sometimes even the sturdiest units need some care, and sometimes this need appears at an inconvenient moment. In these cases, a warp speed is required, and it’s available in the form of  Vaisala’s Care agreement, which is offered for any refractometer models for the platforms PR-23, PR-33, and PR-43, and for the Vaisala Polaris PR53.

Our Care agreement includes planned health checks and preventive maintenance service, and in case the product needs deeper care at Vaisala, we also provide free shipping and priority order handling, and more. The price is fixed for the entire duration of the agreement, allowing for planning, budgeting, and buying the needed services for years ahead. The agreement length can be customized for between 3-5 years.

Many factories or mills have multiple process refractometers in different installation positions and process conditions, exposing some products to harsher environments. Our Care agreement allows flexibility as all of your process refractometers* are automatically included in the agreement.

The Care agreement is a perfect solution for anticipating the unexpected by checking in on your measurement device regularly and preventatively. To buy the Care agreement from Vaisala, contact Vaisala sales


*Our Care agreement applies to product platforms PR-23, PR-33, and PR-43, and Polaris PR53.
