mminhas44 Posted March 2, 2011 Share Posted March 2, 2011 how to calibrate a blood bank refrigerator/ freezer thermometer if one does not have access to a "National Institute of Standards andTechnology (NIST)-certified thermometer or thermometer with NISTtraceable calibration certificate" (like outside USA)? what should be taken as the reference thermometer?

L106 Posted March 2, 2011 Share Posted March 2, 2011 Those are the only reference thermometers that I am aware of. Are you at a hospital? Do you have access to a Clinical Engineering or BioMedical Department? (I know our hospital's Clinical Engineering department has an NIST traceable calibrated thermometer.....Is there some outside institution that could help you?)

Eoin Posted March 4, 2011 Share Posted March 4, 2011 Hi,There are commercial metrology companies that are ISO accredited for this purpose. If you are using your own thermometer to measure temperature of blood fridges, or any other equipment, you will need to have the thermometer calibrated annually. Also you will should calculate the "Uncertainty of Measurement" and include that in your validation of any equipment you are testing with it.CheersEoin Link to comment Share on other sites More sharing options...
