IVF Thermometer to verify that any temperature-controlled equipment
is performing as desired. The unit is waterproof and is calibrated for use
with refrigerators, incubators and heated stages.
Intended Use
To measure the temperature of temperature-controlled equipment
typically used in a IVF laboratory.
Contraindicaon: It is not intended that this device come into direct
contactwithanyssuesamplesbeingtreatedinaclinicalseng,orwith
media which is in direct contact with such samples.

Probe
The IVF Thermometer is supplied with a miniature thermocouple which
is ideally suited for temperature measurement in small volumes of liquid.
AlsoavailablefromRI is a robustprobesuitableforlarger volumesof
liquid,andacryo-probeopmisedforcryopreservaontemperatures.
Connecttheprobetothesocketatthetopofthemeterandghtenthe
screwcollar.Removethewhiteplascsleevefromtheprobepbefore
use, but keep the sleeve to protect the probe when it is not being used.
Note:Thepoftheprobeismadewithverythinwires.Alwayshandle
the probe gently to minimise the risk of breakage.
Using the IVF Thermometer
Turn the meter on by pressing the ONbuonforabouthalfasecond.
Themodelnumber“2110”willashinthedisplaybrieyandthemeter
will begin measuring.
Press the HOLDbuontofreezethecurrentlymeasuredvalue.Thiscan
beusefulwhenwringdowntemperatures.Thesymbolwillshow
on the display. Press the HOLDbuonagaintoreturntothelivedisplay.
Toswitchthemetero,pressandholdtheOFFbuon.Themeterwill

Media Measurement
To check the temperature of media in a culture dish we recommend
preparing a test dish in your normal manner but with water drops instead
ofculturemedia.Theprobepiswaterproofsothepcanbeimmersed
directlyinthewaterdrop.Allowthereadingtoselebeforerecordingor
adjusngthetemperature.Theprobecanbeheldbyhandorplacedinthe
holder supplied.
Incubator Measurement
If the incubator has a dedicated access port for temperature measurement
then pass the probe through this port and ensure it is correctly sealed.
Otherwise, the probe cable is thin enough to pass through the door seal.
Refertotheincubatorinstruconsforfurtherdetails.
Contraindicaon:Itisnotintendedthatthisdevicecomeinto
directcontactwithanyssuesamplesbeingtreatedinaclinical
seng, or with media which is in direct contact with such
samples.

Surface Measurement
AkitcontainingheattransferpasteandsuitabletapeisavailablefromRI.

1. Squeezeasmallamountof
heat transfer paste onto the
surface to be measured.
2. Insertthepoftheprobeinto
the paste.
3. Cut a short piece of the adhesive tape provided and secure the probe
to the surface by placing the tape lengthways as shown. If the tape is
placed across the probe it can fall out easily.

Care and Maintenance
Immersioninmediasoluonswillacceleratecorrosionoftheprobep
due to the salt content of the media. Similarly, long-term exposure to
humidiedairinsideanincubatormayacceleratecorrosion.Toprolong
the life of the probe, we suggest using plain water drops instead of culture
mediawhencheckingthetemperatureinaPetridish(seepage5).
Aer each use, rinse the probe p in plain water, blot dry gently and
allowtoairdry.Thenreplacetheplasccapbeforestoring.
Troubleshoong
Displayshows“O-C”(opencircuit);thismeanstheprobehasfailed.The
mostcommoncauseoffailureisabrokenwireatthep.Failedprobes
cannot be repaired and must be replaced.
Calibraon
WerecommendcalibrangtheIVFThermometerannually.Thiscanbe
done by RI, but it may be more convenient for most users to use a local
testcompany.Werecommendcalibraonbeconductedbyatesthouse
accreditedtonaonalstandards.Themetershouldbecalibratedtothe
specicaonsshownonpage8.
Calibraondoesnotinvolveadjusngthemeter,rathercomparisonto
a traceable standard oset. For example, if the calibraon cercate
shows a reading of 37.3°C at an actual 37.0°C then the meter will do this
consistently.Thisosetcanbeallowedforwhenmakingmeasurements.
Replacing a probe always requires a new calibraon. Similarly, the
meter can be used with more than one probe, but each probe should be
calibrated separately with the meter, and care should be taken to apply
thecorrectosetforeachprobe.
Thecryo-probedoesnotrequirecalibraonastheinherentaccuracyis
sucientforthepurpose.See thespecicaontableonthefollowing
