In-line Refractometer （Economical）
Model : CZ15/CZ53
ZHYQ Sensor&Control Page 1of 11

The In-line Brix-Monitor （Economical））CZ15/CZ53 is a refractometer that detects the Refractive Index of a
sample and outputs
the Brix(%) can also transmit measured data to external devices via 4 to 20mA or RS485 .
CZ15/CZ53 series has the function of automatic temperature compensation according to the temperature of the
tested medium , when the tested medium temperature changes , the Brix value ( soluble solids ) after temperature
compensation is displays and the output changes accordingly
If the Refractive Index of air under atmospheric pressure is 1, then when
light enters medium χ, the ratio of the sine of the incident angle α
measured against the phase boundary to the sine of the refracting angle
β is called the Refractive Index of the medium χ.
The Refractive Index varies with the wavelength of light and
temperature and is represented as follows:
For example: Refractive Index of water at 20℃under the D-line is: = 1.33299: , (Generally expressed as
nD = 1.33299.)
The Refractive Index of a substance varies with temperature. Thus, when using a refractometer to measure the
Refractive Index of a liquid, the measurement value will vary with the sample temperature. The CZ15/CZ53 always
detects the prism temperature. The value of the measurement is automatically corrected for temperature by a
built-in processor, so that the displayed value is equal to the value measured at 20℃ (provided that the sample
temperature is within the range of 5 to 85℃) ,the Brix(%) values are automatically temperature compensated .
n ：Represents the Refractive Index
t ：Temperature (℃)

Inline real-time monitoring and control of liquid substance concentration in various industries
Cutting oil , mold release agent , quenching liquid , cleaning liquid , emulsion in the machining industry
Chemicals and allied , pulp & paper , tobacco , environmental protection
Biorefining , Metals and mining
Food industry , Dairy , Beverage industry , Fruit and effect processing
Starch sweetener , Sugar and sweeteners
Water-based solutions
In factories that produce liquid products such as beverages, medicines, chemicals, etc., the raw materials (stock
solution) must be processed in multiple processes, or two or more mixed solutions must be added through multiple
production lines and multiple processes, such as: juicing, filtering , cooking, dilution, blending, mixing, fermentation,
etc., each process, the concentration will change. If only detectthe finished product concentration, when there is a
substandard product, it is impossible to know which process has the problem, and the produced defective product
causes cost waste. Therefore, an online refractometer is installed on the production line (production pipeline, tank)
of each process. , It can continuously detect the concentration of samples in the pipeline in real time, monitor the
quality of samples in each process, and discover unqualified products in time, which can reduce production costs,
improve the pass rate and product quality. cost, improve inspection efficiency, real-time display of brix value , and
intuitively guide production personnel to operate.

Mounting Precautions
Mounting diagram :

①Install the CZ15/CZ53 so that the prism surface is at a
right angle to the ground.
②Attach the flow pipe to the CZ15/CZ53 with
O-ring (accessory) inserted between them, and fasten
them together with the clamp band (accessory).
③The prism surface may become contaminated with
solids, dirt and/or grease. If this happens, the prism
surface must be cleaned by hand.
Note : Cleaning the Prism instruction in the next page
The sample inlet unit should be installed in such a
manner that it can be easily removed to allow access
to the prism for cleaning
Note : Suspending the CZ15/CZ53 when using the
sample inlet unit to connect to the piping is dangerous ,
Use of the optional stand is recommended.

Mounting procedure:

◆If the sample solution could potentially stain the prism, immediately clean the prism after measurement .
◆Before running hazardous substance(s) through any precautions should be taken to ensure the safe handling of
the hazardous system, necessary substance(s). If using a sample inlet unit, use caution when disconnecting the
CZ15/CZ53 .
◆Cleaning liquids up to 150℃ can be used for CIP or SIP . The cleaning liquid can be used safely for 30 minutes
at one time. The momentary difference between the sample liquid temperature and the cleaning liquid temperature
must be no more than 80℃. When using cleaning liquids at temperatures over 150℃, the power source (DC24V)
must be turned off.
◆Detach the clamp band that connects the main unit to the sample inlet unit, piping or tank.
◆Clean the prism surface carefully with a soft tissue soaked with warm water or ethyl alcohol. If the sample
solution contains oil or grease, use ethyl alcohol
to ensure the prism surface does not develop a film. Development of a film on the prism could cause erroneous
measurements.
◆NEVER clean the prism with an abrasive material.
◆ Cleaning the prism with an abrasive material could cause scratches on the prism which could lead to erroneous
measurements.
◆After cleaning is complete, re-attach the CZ15/CZ53 unit to the sample inlet unit, piping or tank. The procedure is
described on the instruction manual.
Note :we also can supply Auto or manual washing device for optional, if need , Please specify when
confirming the order

Cleaning the Prism

◆ If the unit begins to overheat, smoke, or emit an abnormal smell , immediately turn off the power and unplug the
unit from the power supply.
◆ DO NOT measure any sample that can damage the prism or the sample inlet unit , sample temperature should
be kept between 5℃ and 100℃ when the power is turned on .
◆ Do not put the instrument in a damp place, Maximum average relative humidity: 95% RH (25℃);
◆ Atmospheric pressure: 80kPa ~ 106kPa;
◆ Places where there is no corrosion or destruction of insulating gas, steam or dust;
◆ Use the instrument at altitudes below 2000 meters (altitude).
◆ Use the instrument indoor.
◆ Do not change the ambient temperature of the instrument suddenly
◆ Do not use instrument in areas with large amount dust and strong vibrations
◆ Do not put the instrument in low temperature place
◆ Do not put heavy objects on the instrument
◆ Do not install the instrument In direct sunlight or near the heating source.
If measurement of concentration transmitter is abnormal, please check input power supply first. If power supply is
ok, check if the measurement window of transmitter has been covered by contamination or not, and make sure
that measurement window can contact solution well at the mean time. If it is problem of transmitter itself, please
return it to the factory for maintenance.
◆ Protected from direct rain and snow, the packaged transmitter can be applied to various modes of transportation,
such as water, land and air transportation.
◆ The packaged transmitter can be stored for more than 12 months with temperature ranging from -40℃~60℃,
and relative humidity less than 90%
◆ Live plug-in and pull-out should be strictly prohibited under live working condition, otherwise, it will damage the
concentration and infrared transmitter easily.
