Cool Incubator Calibration SOP




1.0  OBJECTIVE:
To lay down the calibration procedure of Cold incubator to provide a system to calibrate, control and maintain the equipment used for inspection measuring and test equipment in order to ensure the correctness of measurement and test status.
2.0  SCOPE:
This shall be applicable to the Cold incubator of Quality Control Instrument Laboratory.
3.0  RESPONSIBILITY:
3.1  Technical Assistant/ Helper.
3.2  Q.C Analyst.
4.0  ACCOUNTABILITY:
4.1  Manager-Quality Control.
5.0  MATERIAL AND EQUIPMENT:
5.1  Cold incubator.
5.2  Calibrated thermometer.
6.0  PROCEDURE:
6.1  Make sure that the instrument is clean follow the SOP.
6.2  Operate the apparatus according to the SOP.
6.3  For the calibration of Cold incubator use a standard thermometer ranging up to 300oC.
6.4  Start the calibration procedure after 1 hour of starting the Cold incubator.
6.5  Set the Cold incubator at 4oC temperature.
6.6  Put the standard thermometer in upper shelf of Cold incubator and close the door of it.
6.7  After some hours opens the door of Cold incubator and read the temperature of standard thermometer randomly and match the observed temperature of thermometer.
6.8  Repeat the above procedure by putting the thermometer in lower shelf for some hours.
6.9  Record the observed temperature in calibration record of Cold incubator as per annexure-1.
6.10    The observed temperature of thermometer in both shelves should be ±0.5oC tolerance limit to the set temperature value.
6.11    Record the result on the “Calibration Record”, “Calibration Log Book” & paste the “Calibration Status Sticker” on Cold incubator.
