1-1. Measurement Principle
The absorption band of water has three wavelengths
in the near- infrared spectrum area, 1.2, 1.45, 1.94
micrometers. When a sample is irradiated with light
of those wavelengths, the sample will absorb light in
an amount commensurate with its moisture content.
The sample's moisture content determines how much
light the sample will absorb. this moisture content
can therefore be determined by measuring the light
attenuationproducedbythesample.
However,whenmeasuredonlyabsorptionwavelength,it
can notmeasuredstablysinceinuence ofthe surface
stateofthematerial,thesizeoftheparticles,thecolor,
etc. Therefore, the KB-30 is using also reference
wavelengthwhichishardlyaffectedbywater.
1-2. What's the Calibration Curve?
NIRmoisturemeterismeasuringthemoisturecontentby
convertsfromthenear-infraredabsorptiondegreeofthe
object.Todothisberequiredtheformulaforconverting.
This conversion formula is the calibration curve. The
calibrationcurvedependonabsorptioncharacteristicsof
the measurement object. Therefore, It must be created
forpereachobjectbeforemeasurement.
* Please contact to your dealer, if you would like to know
how to make calibration curve.
* Please use proper calibration curve that is made for
each sample correctly.

3. How To Use
● Calibration curve
Itisnecessaryto setthe calibrationcurveto theunit beforemeasurement.Pleasemakethe
calibrationcurvebythesuppliedPCsoftware,thensetittotheunit.
● The ground of power cable
Thereisariskofreorelectricshockifthegroundwireofthepowercableisnotgrounded.
When outlet is 2 pins, use the conversion plug for ground. When outlet is 3 pins and it is
grounded,KB-30willbegroundautomatically.
● Vibration in environment>
KB-30shouldbeinstalledinaplacewherevibrationissmallaspossible.Ifitwillbeinstalledin
aplacewherethereisvibration,shouldbesuppressthevibrationbyseparatingtheinstallation
standofKB-30fromthevibrationsource.
● Environmental temperature
KB-30mustbeusedin5to35°Cambienttemperature.Ifyourenvironmentisnotinthisrange,
itisrequiredthe system toseparatetheambienttemperaturefromenvironmenttemperature,
suchasoptionalCoolingboxwhichcanbereceivethecoolingdryairtoinside.
● Moisture
KB-30mustbeusedintheplacewherehasnocondensation.IncasethatKB-30isusedinthe
placewherehasmuchmoistureorhighsalinity,thereisariskofcorrosionandoxidationofthe
connectorpartandsoon.Pleasedoregularchecksandcleaning.
● Protection against dust
The air purge hood is installedKB-30. If you wouldlike to use it intheplace wherethere is
muchdust,werecommendairpurge.Pleaseuseexternaldiameter6mmφtubetoconnectair
sourcesuchaspumpandcompressor.(Thetubeisnotattached.Pleasepreparebyyourself.)
Thestandardofamountusedofairis0.5-1.0kg/cm2(about70-140NL/min).Pleaseuseclean
dryairwithoutwaterandoilwhenyouuseairpurge.
● Sunlight
PleaseuseKB-30afterthelight-blockingtreatment,becausethestronglightasdirectsunlight
willdisturbthemeasurement.
● Consumable goods
Werecommendthereplacementofconsumablegoods(FilterWheelMotor, Lamp)everytwo
yearstomaintaintheaccuracy.Pleasedon'treplacethembyyourself.Pleasecontacttoyour
dealer.
● Inspection
whenyoudonotuseKB-30foralongtime(6monthsormore),ifyouwanttouseitagain,we
recommendtheinspectionofKB-30.Pleasecontacttoyourdealer.
Please read before use
* If KB-30 is installed in a place where corrosive gas is generated, it may cause a malfunction.
If you would like to install it in such a place, please contact to your dealer in advance.
