In-Line refractometers are designed to monitor and control the concentration of dissolved solids or water soluble liquids in your process lines. These instruments can be incorporated in piping of manufacturing plants, liquid mixing devices, and washing apparatuses to continuously measure the concentration of various liquids. In-Line refractometers are suitable for use in the control of mixing, concentration, fermentation, and control of the concentration of water-based or alkali-based detergent, etc.
The light from an LED source is transmitted by a fiber optic onto one side of a measuring prism and internally reflected to the interface of the prism and the sample liquid. A portion of this light beam is reflected back onto the opposite side of the prism at an angle which depends on the refractive index of the liquid at the interface. The position of this reflected beam, as it exits the prism, changes with the angle of reflection (which depends on the refractive index of the sample). A linear diode array is used to accurately detect the varying position of the reflected beam, and this position is calibrated with respect to refractive index. As there are no moving parts with in-line refractometers, only precise optical and electronic elements, the calibration is very stable, repeatable and accurate.
To connect the in-line refractometer to your system you simply attach the unit to a piping system to monitor food or beverage production, pharmaceutical production, industrial fluid, washing devices, dilution/mixing devices, etc. The in-line refractometer will continuously monitor water content and mixing ratio with successive measurements of refractive index, Brix, or concentration.
The ATAGO Model PRM-100α In-Line Refractometer is just such an instrument. It can provide the following:
• Wide range 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.
