SMARTREF OVERVIEW
ABOUT THE DEVICE
The digital refractometer SmartRef measures the refractive index of liquids. In addition, a temperature sensor measures
the sample temperature directly at the sample area. The refractive index of a pure material is a physical property and can
be used to identify and characterize materials. The refractive index of a dissolved substance in a solvent correlates with
its concentration and can therefore, be used for concentration measurements. Many other scales can be derived from the
refractive index.
You operate and control the device via the mobile app running on your smartphone. For the communication between the
device and your smartphone, Bluetooth Low Energy is used. Via the app various measurement units based on the refractive
index can be calculated (e.g. %Brix).

MEASUREMENT
GENERAL INSTRUCTIONS FOR MEASURING
Fill the sample area to the indicated line in the sample well. A minimum sample volume of 0.4 mL is required for proper
operation.
For best measurement performance, ensure that the sample temperature does not deviate signicantly from the ambient
temperature. When measuring hot/cold samples, allow the measurement area temperature to equilibrate. Depending on the
temperature difference between the sample liquid and the device, this may take only a few seconds or up to a minute.
Prior to each measurement ensure that the prism and sample well are clean and dry.
Carefully clean the device after each measurement series to avoid deposits in the sample area. Have suitable solvents for
cleaning at hand.
The measurement performance can be deteriorated by excessive ambient light (sunlight, articial light). Make sure the sample
area is not exposed to direct irradiation. If you are using the device in a bright environment, it might be necessary to shield the
sample area from direct light.
Use plastic syringes or pipettes to apply the samples. Metal devices or other hard subjects (e.g. spoons, tweezers) may
scratch the glass prism, causing permanent damage to your device.
Sample containing dissolved CO2will cause bubbles, which can lead to invalid measurement results. Degas your sample
carefully before measurement. For samples containing suspended solids it is recommended to ltrate the sample.

12
CAUTION!
Handling samples with temperatures of more than 50 °C (122 °F) bears the risk of burns. Wear appropriate protective clothing
or take other protective measures when you handle hot samples.
PERFORMING A MEASUREMENT
Properly clean the prism surface and the surrounding sample well.
 Apply the sample on the measuring surface using a plastic pipette or plastic syringe until the sample well is lled up to the
marked height.
Start measurement via the app.
The app displays the result of the measurement.
TIP
If errors occur during the measurement process the app will provide respective information.
It is recommended to perform a zero-adjustment daily before measuring (see 9.2) and if changes in ambient conditions have
occurred.
If the sample has a signicant different temperature compared to the device or the device temperature differs signicantly
from the ambient temperature allow the sample temperature to equilibrate for a short time (approximately 1 minute).
In between measurements of different samples make sure to clean the prism surface and the sample well properly and dry it
prior to the subsequent measurement to avoid cross contamination.
After a certain time of inactivity (duration selectable via the app) the device will shut of automatically.
CLEANING AND STORING THE DEVICE
CLEANING ROUTINE AND CLEANING AGENTS
After each sample measurement with the device always clean the prism surface and the sample well using ultra-pure water or
ethanol.
You may need to clean it more often when you are going to measure a sample that could chemically react with the previous
sample or when you are going to measure a sample that is not miscible with the previous sample.
Remove the sample via rinsing the sample area with a suitable liquid, e.g. ultra-pure water or via absorbing the sample using
a soft tissue. If you did not use ultra-pure water as cleaning liquid, additionally rinse the prism surface and the sample well
with ultra-pure water to remove any other cleaning liquid. Finally, empty the sample well and use a clean, soft cloth (cotton or
microber) to dry off any remaining droplets.
Clean the housing and the sample area with a soft cloth dipped in ethanol or warm water. If necessary, you can use a mild
solvent (pH < 10).

13
CAUTION!
Do not use dirty or rough cloths for cleaning/drying the sample area, since this could cause scratches on the prism surface
and permanently damage your device.
Do not submerge the device in water or any cleaning agents or other liquids.
Particulate material suspended in sample liquid or the use of an abrasive cleaning agent may lead to scratches during the
cleaning process. This can damage the device permanently.
CAUTION!
Do not use aggressive solvents (e.g. Acetone) to clean the device. Only use approved and compatible cleaning agents,
otherwise your device could suffer permanent damage.
NOTICE
The inside of the device does not require cleaning. Only clean the exterior housing and the sample area.
NOTICE
It is recommended to use ultra-pure water instead of tap water because tap water can cause limescale buildup in the sample
area, leading to a deterioration of the measurement quality.
NOTICE
Dispose samples and cleaning agents according to legal regulations.
STORING
Before you store away the device, clean it as described above. If you are going to store your device for a longer period of time,
remove the batteries.
CAUTION!
Store the device in a dry environment. Do not store device in direct sunlight, low or high temperatures.
CHECKS AND ADJUSTMENTS
It is recommended to check the measurement performance of the device prior to a new series of measurements. If you get a
result that deviates from the target value of your sample by more than the given tolerances, you need to adjust the device by
performing a zero adjustment.

14
CHECK MEASUREMENT
Fill the sample well with ultra-pure water up to the sample height indication and perform a measurement via the app.
Depending on the selected unit of measurement, the result should be e.g. 0.0 °Brix, 0 ppt, etc. within the respective accuracy.
A water check should be performed before starting measurements. Perform additional water checks on demand, depending
on your judgement, e.g. when you get a series of unexpected results. If the check fails, take corrective actions until the check
is valid again:
Check the reference liquid (ultra-pure water) quality
Clean the measuring prism thoroughly. Alcohol or a solvent suitable for the samples measured before could be useful.
If above actions do not help to perform a valid check, perform a zero adjustment.
TIP
For best measurement performance use a new and clean pipette for every measurement.
ZERO ADJUSTMENT
Before measuring, performing a zero adjustment using ultrapure water is recommended.
Properly clean and dry the prism surface and the sample well.
 Apply ultrapure water on the measuring surface until the sample well is lled up to the marked height.
If the sample temperature differs strongly from the device temperature allow the sample to equilibrate for approximately 1
minute.
Perform zero adjustment via the app.
The app will indicate if the zero adjustment process was successful or provide further information otherwise.
TIP
Perform the zero adjustment under the same conditions as the sample measurement. Changes in ambient conditions
between the zero adjustment and the sample measurement could lead to deviations in the measurement result.
If the zero adjustment is performed under strong light (e.g. sunlight) ensure a proper shading of the sample well during the
adjustment process.
EXCHANGING THE BATTERIES
For proper battery handling, observe the safety instructions. The battery status of the device is indicated in the app. When
the batteries are depleted, the device switches off by itself. If the app indicates a low battery or the device does not switch on
it is advised to replace the batteries. Use only batteries type AAA LR03 (alkaline) or rechargeable batteries type AAA HR03
(NiMH).

15
CAUTION!
Turn the device off prior to exchanging the batteries.
Make sure the sample area is empty and dry before exchanging the batteries to avoid spillage of liquids.
Only open the device in a clean and dry environment.
The inside of the device does not require any cleaning. Do not use liquid cleaning agents on interior parts of the device.
Do not open the compartment containing the optical and electronical components of the device as this will void the warranty.
STEPS TO EXCHANGE THE BATTERIES
Unscrew the bottom cover of the device using an Allen key (2 mm; 5/64 in)
Remove the empty batteries.
Insert the fresh batteries with the correct orientation!
 Reattach the bottom cover and tighten the screws rmly.
