HOW TO ANALYZE THE MILK
Step 1:
Fill the measuring mug with milksampleto be measured. Dipthe tube (sucker) into the milksample
and place the measuring mug on the Ekomilk working surface.
Step 2:
pH and temperature measurement:
Gentlyremove the protective plasticcap from the pH electrode beforeproceeding with measurement.
Use de-ionized ordistilled waterto rinse the electrodebeforeuse. Thiswill remove impurities that
have adhered on the electrode body. Rinsingwill also serve to activate the electrode, especiallyifit
has been dehydrated(inwhich case you may have to soak the electrodeinwaterfrom 10 minutes
onwards (See Section“pH Measurement -Additionalinformation”).Fill anothermeasuring mugwith
the same milksample. Dipthe electrode and temperaturesensor(fig.1 –pos. 6,7)intothesample. Be
surethatthe electrode iscompletelyimmersed intothe sample. Stirthe mug gentlytocreate a
homogeneous sample. Place it on the Ekomilkworking surface. Formoreinformation, see “pH
MEASUREMENT -ADDITIONAL INFORMATION”.
Remark: EKOMILK BOND uses3sensorsformilkparametersmeasuring –ultrasound, conductivity
and pH. Load on both measuring mugs the same milk and to get correct results atonce.
Step 3:
Press MODE and by means of the search buttons , ▼select the desired mode:
rCOW MILK -analysis of cow milk
rSHEEP/BUFFALO/ GOAT/HOMOG.MILK -analysis of sheep/buffalo/goat milk
When the propertype of milk is displayed, press OK to startthe measurement.

2. Do notmove theAnalyzer while themeasurementis going on. This mightcause result
deviations outofthe spec limits.
3. Incase ofair bubbles presentsin the measuring camera the message EMPTY CAMERA
appears on the display. Throw outthe sample and repeatthe measurement.
4. Incase ofmotorproblem the message MOTORERROR appears onthe display. Switchoff
the device, waitfor1minuteand then switch iton again. Ifthe problem persists, please contact
your dealer.
Remark:
1. To get precise pH results, calibrate the pH measurement systemat least twice weekly.
2. Ifsomeone of pH ortemperaturesensorsaredisconnected orthe received results areout of spec
limits orthereisdamage inthemeasuringsystem,you will have messageERR instead of pHor
temperature results.
3. The pH resultisvalidwhen thereisR(Ready)behind the valueon the display. Otherwise make a
new measurement to get a correct result.
4. pH measurement isstronglyrelated to the temperature. Ifthe temperaturesensordoes not work,
the pH result willbe referred to the default temperature of 25°C. The accuracy would be out of range.

CLEANING
This section is togive directions for dailyand periodical cleaning ofmilk analyzers Ekomilk in
order to assure their long life and proper functioning.
ULTRASONIC SENSOR CLEANING
1. DAILY CLEANING
Daily cleaning is required when:
-The intervalbetween two consecutive measurements is morethan half of one hour;
-The daily job is finished.
1.1. Cleaning outwhen the interval between twoconsecutivemeasurementsismore than half
an hour.
Steps:
1.1.1. Fill the measuring mug withclean andwarm, but not hot, and clean water(40°-60°C).Dipthe
tube (sucker) into the waterand place the measuring mug on the Ekomilk working surface.
1.1.2. Pressthe MODE button once. Press the searchbuttons , ▼to select CLEANING option.
Confirmwith OK.The display shows message CYCLES01 -numberofcleaning cycles tobe done.
One cleaning cyclepumps the waterinandout of the sensorfive times. Press the search buttons ,
▼to setthe desired numberof cleaning cycles. Thisnumbercan change from 1to99. We
recommend one ortwo cleaningcycles to be chosen.When thedesired numberisdisplayed, press
OK to startthe cleaning. Whenthe CLEANING stage isoverCLEANINGEND isshown on the
display.
1.1.3. Remove the mug and throw away the muddy water.Repeat thisprocedureseveraltimes till
clean watercomes outfromthe Analyzer.
1.1.4. Done.
1.2. Cleaning outatthe end ofa working day.
Thisprocedureprevents formation and collection of fatand “Milkstone”deposits into the sensor.Milk
stone consists ofmilksolids, calcium, magnesium, iron, sulfates,etc. Milkand watermineraldeposits
become hardened andlayered on the sensorand vinylpipes innersurfaces, which contact with milk
and disturbs the milkanalyzerwork. Cleaning willbe effective ifareagent which attacks the “milk
stone”isused. We recommend 2% solution of the alkaline cleaner EkoDay to be used as adaily
cleaning solution.
Preparation of 2% EkoDay working solution:
a.Use pipette to add 10 mL EkoDay to glassware with 490 mL distilled water.
b.Put into a labeled container.
Take care this solutiondoes not contact youreyes orskin!
Attention!Use only2%EkoDayworking solution as acleaning agent.TheEkoDayconcentrate
can damage your analyzer!
Steps:
1.2.1. First clean the analyzerwith pure wateras it is described inprocedure 1.1. (see above).
Attention!Always clean analyzerwith purewater before using the cleaning agent. Using 2%
solution ofthe alkaline cleaner EkoDaywithoutfirstcleaning analyzer for removing the fats
and proteins will resultinfixing the “milk stone” to the surface.

1.2.2. Fill the measuring mug with2%solution of the alkaline cleaner EkoDay (25°-40°C),dipthe
tube (sucker) into thecleaning solution andplace the measuring mug on the Ekomilkworking surface.
Put the analyzerincleaning mode, set 20 cycles andpress the OK button.When the CLEANING
stage is overCLEANING END isshown on the display.
1.2.3. Fill the measuring mug with clean water,puttheanalyzerincleaningmode, set 5cycles and
press theOK button.When thisprocedureisdone, remove themug and throw away the water.Fill the
measuring mug with clean waterand repeat this procedure 3-4 times.
1.2.4. Done
2. PERIODICAL PROCEDURE
To ensureagood workof the MilkAnalyzer itisadvisoryto clean the deviceat least once aweek
strictly performing underwritten procedure.
This procedure uses 5% solution of acid cleaner EkoWeek as a periodicalcleaning solution.
Preparation of 5% EkoWeek working solution:
a. Use pipette to add 25 mL EkoWeek to glassware with 475 mL distilled water.
b. Put into a labeled container.
Take care this solution does not contact youreyes orskin!
Attention!Use only5%EkoWeek working solution asacleaning agent.The EkoWeek
concentrate can damage your analyzer!
2.1. Perform the daily cleaning first.
Attention! Make surethat the analyzerisproperlycleaned with purewaterbeforegoingon to the next
item oftheprocedure. Mixing both cleaningsolutions-alkaline EkoDay and acid EkoWeek willresult
in forming “milk stone”.
2.2. Fill the measuring mug with 5%solution of the acidcleaner EkoWeek (25°-40°C),dipthe tube
(sucker) intothe cleaning solutionand place the measuring mug onthe Ekomilkworking surface. Put
the analyzerincleaning mode, set 40 cycles and press the OK button. Whenthe CLEANING stage is
over, CLEANING ENDis shown on the display.
2.3. Open the top coverby pressing its left side – fig. 3 – step 1.
2.4. Remove the plug as it is shown on the fig. 3 – step 2.
2.5. Insertthe plungerinstead of the plug – step 3.
2.6. Fill themeasuringmug with clean andwarm, but not hot, water(40°-60°C),dipthe tube (sucker)
into the waterand place the measuring mug on the Ekomilk working surface.
Move up and down the plungerseveraltimes. Remove the mug and throw away the water. Fill the
mug with clean and warm waterand repeat this step 4-5 times – step 3.
