PRM series
8 Reasons to Choose Our Inline Refractometer

High accuracy for low concentration samples.

High accuracy for low concentration samples.

The PRM series measures the Refractive Index, Brix, concentration/water content, mixing ratio, etc. of various solutions with high accuracy. In particular, the PRM-2000α can measure low-sugar beverages, cleaning solutions, wastewater, etc. that are below 2.000% Brix with a high accuracy of ± 0.007%.

Measureable at low and high temperatures.

Measureable at low and high temperatures.

The PRM series is equipped with automatic temperature compensation (ATC) and supports a wide range of temperatures from 5 ° C to 100 ° C (PRM-2000α is 5 to 90 ° C). Since the wetted surface can handle up to 160 °, use CIP and SIP cleaning with confidence!


Flat Sample Stage

Flat Sample Stage

By making the sample stage (wetted part) completely flat, the adhesion of the sample liquid to the prism surface is minimized and is more hygienic. The prism stage is re-polished in 1/100 mm increments during manufacturing to eliminate the chance of slight uneveness that may occur between the prism surface and the prism stage.

Enhanced Cleaning with a Prism Wiper or Ultrasonic Cleaner

Enhanced Cleaning with a Prism Wiper or Ultrasonic Cleaner

Due to their nature, some sample liquids will adhere or build up on the prism no matter what after longterm use. For these cases, ATAGO has designed both prism wiper and ultrasonic cleaning devices. Using either of these means is no need to stop the line or remove the in-line refractometer many times just to clean the prism when buildup occurs.

Compatiblity with strong acids and strong alkalis (Hastelloy / Titanium)

Compatiblity with strong acids and strong alkalis (Hastelloy / Titanium)

For use with harsh chemicals, the wetted part of the PRM series can be customized. The PRM series is standard stainless steel but can be changed to Hastelloy or titanium by request. Because all the metal is shaved and polished in-house, we can flexibly respond to changes in materials.


Customizable User Scale

Customizable User Scale

In addition to Brix and refractive index, the PRM series has an additional special scale feature that will display the concentration % of a specific sample.Customers can customize their PRM inline refractometer's special scale by preparing and entering the sample's "refractive index vs. concentration (all temperatures)" data.If data is provided beforehand, we can also input the data for the customer instead.

38 years of long-selling, reliable quality

38 years of long-selling, reliable quality

Customers must stop production if there is an issue with the system or inline refractometer, which can cause a big impact.For that reason, reliability and a good track record are important points.The PRM series is a long-selling product that has been highly acclaimed around the world for 38 years.ATAGO provides excellent support and aftercare service from offices and service center around the world should you encounter any issue.

Alarm Function

Alarm Function

The PRM series is equipped with a function that outputs an alarm signal when a value that exceeds the set control range is detected.This is a very convenient function to quickly detect nonconformities in the production line.Using relay drive, it is possible to detect and control the occurrence of abnormal values ​​by lighting the alarm lamp, inputting to the sequencer, etc.Moreover, as a data output function, the recorder output (DC4mA ~ 20mA) and RS-232C output are an option.

Case Study

Tea-based beverage manufacturing example
POINT

Block nonconformities by process

Raw material manufacturing process

Check the concentration of the extract

Manage extraction yield by measuring the Brix of the extracted solution.Depending on the extraction rate, re-extraction may be performed.

Blending process

Mixing Ratio Feedback System

The mixing ratio can be detected in real time, and feedback is given so that there are no non-standard products.

Filling process

Pre-Bottling Final Check

A final check on the product before bottling is made to make sure it is within specifcations.It can also be used to reduce liquid loss by controlling the switching to water during cleaning.

Product details

In-line Refractometer PRM-100α

The unit measures the refraction of light generated between the prism surface and a liquid sample. The PRM-100α is upgraded from the PRM-85 in the following aspects:
• Wider than ever 0.0 to 100.00% Brix range
• Improved measurement accuracy: Brix ±0.05%, nD ±0.00010
• Two options for setting the minimum indication decimal place
• Simple two-piece construction: detection section and operation display section
• Easy-to-read color display panel.
Simply attach the unit to a piping system to monitor food or beverage production, pharmaceutical production, industrial fluid, washing devices, dilution/mixing devices, etc. Continuously monitor water content and mixing ratio with successive measurements of refractive index, Brix, or concentration.
*The prism is specially designed to prevent solid materials from collecting on the surface, even after extended periods of use.
