PR-23-A Vaisala K PATENTS® sanitary refractometer

Vaisala K PATENTS® Sanitary refractometer PR-23-A- suitable for measuring brix and concentration

Hygienic compact refractometer PR-23-ACSuitable for installation in 2.5 "and smaller pipes. The sensor can be connected via a flow cell, sanitary clamps or Varivent®, or it can be mounted directly on the outer corner of the bend.

Sanitary probe type refractometer PR-23-AP Suitable for installation on large pipelines, storage tanks, digesters, moulders and can withstand high temperatures up to 150°C (300 °F). The sensor is mounted in a pipe or container through a 2.5 "or 4" sanitary clamp.

Sanitary flush type refractometer PR-23-APP Install on cooking tanks, cooling crystallization tanks and other sanitary grade containers with scrapers or stirrers. The PR-23-APP sensor is mounted on the bottom flange of the APV tank or through the steam jacket.

The refractometer can perform 0-100 Brix full scale measurement. The accuracy is usually ±0.1 Brix, and temperature compensation is automatically performed during measurement. Low and high concentration alerts can be configured. Due to the digital sensing technology, even a large number of suspended particles, air bubbles, or color changes do not affect the measurement or accuracy.

Each sensor is accompanied by a calibration certificate, which is issued based on the comparison of a set of standard liquids with the actual sensor output. The calibration and accuracy can be verified in the field using a certified refractive index liquid and through the Vaisala calibration program.

characteristics:

1. Each sensor is aligned: free interchanges can be made between all sensors。

2. The refractive index (nD) measurement ranges from 1.3200 to 1.5300, corresponding to 0 to 100 Brix。

3. 3-A hygiene and EHEDG certification

4. Resistant to CIP and SIP cleaning

5. Dual connection: one transmitter can run two sensors independently. The second sensor can be easily integrated in the near future.

6. Full digital system: particles and bubbles do not affect operation or accuracy.

7. CORE-optics Optical module: no drift, no re-calibration, no mechanical adjustment.

8. Users can use Ethernet connection and remote panel for data logging and remote operation.

9. Process temperature: -40°C... 130°C (compact); To 40 ° C... 150°C (probe type).

10. Built-in Pt1000, fast temperature measurement and automatic temperature compensation work.

11. Users can use refractive index standards to easily complete field instrument verification to meet their own quality assurance system requirements.

major advantage:

Health certification

The 3A mark ensures that the sanitary refractometer PR-43-A meets the 3A Sanitary Standard number 46-04 (for refractometer or energy absorption optical sensor measuring fluid concentration) and that it has passed an independent third party verification check authorized for the 3A mark

Maintain accurate and stable measurement at full scale

Measurements are accurate over the entire concentration range from 0 to 100 brix: R.I. nD ±0.0002 typically corresponds to ±0.1 brix or ±0.1 percent by weight. The measurements are not affected by bubbles, particles, colors, or vibrations. The system supports CIP and SIP cleaning.

No periodic maintenance required

There are no moving parts within the refractometer that require regular maintenance.Completely digitize the meter. No drift calibration. No re-calibration or mechanical adjustment is required.
