1. Working Principle
In-line Refractometer Instruction Manual
The in-line refractometer is composed of a light source, Prism, a light receiver and a signal
modulation circuit. The light source emits a stable light signal through the prism to contact
the measured medium, and the corresponding refractive index is generated by the concen-
tration of the measured medium. The optical device calculates the refractive index of the
collected refracted light source to obtain the corresponding concentration through the data
algorithm. Since the concentration is affected by temperature, the internal temperature
calibration is adopted to reduce the influence of temperature drift.

1. Daily maintenance
1.1 If the instrument becomes dirty, please wipe it with a soft cloth. Do not use gasoline, paint thinner, etc.
to clean the instrument.
Maintenance and Troubleshooting
11. Relation graph between concentration value and refractive index
3.1 When there is no signal output from the inline refractometer, first check whether the cable is disconnected or
short-circuited. If there is, replace the cable;
3.2 When the inline refractometer measurement is abnormal, first measure whether the power supply is input. If the
power supply is normal, please check whether the measurement window of the sensor is contaminated and
covered, and at the same time ensure that the measurement window can be in good contact with the measured
solution; if it is not normal, The sensor is faulty, please return to the factory for repair
3. General troubleshooting
2. Regular/timing maintenance (can be operated by cleaning device)
2.1 Wipe the prism of the Inline refractometer clean, and use 0.3mL distilled water to test, if the value is not equal to
4mA, reset it by pressing the button.
2.2 The inline refractometer that measures high temperature, corrosive media or operating under vibration conditions
should be calibrated once every six months
2.3 After the online refractometer has been in operation for 5 years, an insulation resistance test should be carried
out, and the insulation resistance should be above 500MΩ
