The IR100 measures refractive index using the critical-angle method and can convert it to Brix, solids or concentration using a medium-specific calibration curve. Final ranges and conversions should be verified with representative samples.
Do color, turbidity or viscosity affect online refractometer readings?
Critical-angle measurement is generally not directly dependent on sample color, but bubbles, crystals, deposits, flow conditions and prism cleanliness can affect representativeness. Confirm installation and cleaning for viscous or scaling media.
How should I choose an IR100 configuration?
Consider the sanitary compact version for food or pharmaceutical lines, the standard version for general process service, and the high-precision version for metrology or demanding monitoring. High-temperature/high-pressure, hazardous or corrosive media require a separate check of materials, limits and certificates.
Where should an online refractometer be installed?
Choose a location where the measurement surface remains fully wetted, the sample is well mixed and maintenance is accessible. Avoid air pockets, dead zones, deposits and severe pulsation; confirm flow direction, drainage and cleaning access for pipe installations.
Can the IR100 connect to a DCS or PLC?
Depending on the model, isolated 4–20 mA, RS485 Modbus RTU, Ethernet or Modbus TCP can be provided. Confirm channel count, registers and power requirements in the model technical file.
