1. INTRODUCTION TO THE N9005 AND N9094
TheN9005andN9094handheldthermometersrepresent
aleapforwardinspecicationandperformanceandhavea
numberofnewfeatures.
BothinstrumentshavetheexistingComarkpremiumcasefor
ultimatestrengthanddurability.Thisoffersthehighestlevel
ofstrength,durabilityandprotectionagainstdustandwater
ingress.TheinstrumentsarecertiedtomeetIP68.Features
includeaclock,countdowntimer,timeralarms,highandlow
temperaturealarms,selectablesensortype,variableauto-off
anddatahold.
2. N9005 AND N9094 THERMOMETERS WITH
BIOCOTE® PROTECTION
BioCote®isasilverbasedanti-microbialagentthatis
impregnatedintotheinstrumentcaseduringmoulding.
BioCote®effectivelyinhibitsthefunction,growthand
reproductionofawiderangeofmicro-organismsandits
protectionisincreasinglyacceptedaspartofHACCP,due
diligenceandhealthandsafetyprocedurestoreducecross
contamination.BioCote®protectionlastsforthelifeofthe
instrument,becausetheagentispresentthroughoutthecase
plasticandcannotrubofforbewashedorleachedout.
Biocote®activeingredientsareregisteredwiththeUS
EnvironmentalProtectionAgency(EPA).
AlthoughBioCote®inhibitsthegrowthofmicro-organismson
theinstrumentcase,itdoesnotprotectindividualsagainstsuch
harmfulorganismsorremovetheneedtomaintainthehighest
standardsofpersonalandproducthygieneandcleanliness.

4. CONNECTING PROBES TO THE
THERMOMETERS
TheN9094thermometerhasaLumbergsocketforprobe
connectionandofferaclassleadingchoicebetweenComark
thermistor,typeTthermocoupleortypeKthermocoupleprobes.
TheN9094thermometerwillautomaticallydetectthesensor
typeoftheprobeconnected.TheLCDwillthenindicate
thermistorprobesas“PST”,andtypeTorKthermocouple
probesas“T”or“K”.
TheN9005thermometerhasasub-miniatureconnectorfor
probeconectionandoffersthechoicebetweentypeTandtype
Kthermocoupleprobes.
Note:TypeTorKmustbeselectedinthesetupmenu,see

6. DATA HOLD
TheN9005andN9094thermometershaveadataholdfacility.If
the‘II’buttonispressedatanytimeduringnormaltemperature
mode,thecurrenttemperaturewillbeheldonthedisplay.To
releasepress‘II’.
7. COUNTDOWN TIMER
TheN9005andN9094thermometershaveacountdowntimer.
ThisfunctionisactivatedfromtheSetUpMenu–seesection
below,andcanbecalibratedinseconds/minutesorhours.
Pressingthecountdowntimerbuttonwillstartthisfunction.
Pressingthebuttonagainduringthecountdownperiodwillstop
thecount.Theinstrumentwillbeepfor30secondsattheend
ofacountdownperiodtoindicatetotheuserthatithasbeen
completed.
