Calibration of Laboratory Oven
The purpose of the standard
operating procedure is to provide guidelines for calibration
of Laboratory Oven.
The scope of this
standard operating procedure includes calibration of Laboratory

Switch on the instrument.
Ensure that the temperature indicator/controller is in working condition
i.e. the set
temperature should be maintained / retained properly.
4.3 Ensure that the door of laboratory oven is
properly closed and does not loosen
Ascertain and set the points/points at
which calibration is required.
4.5 Switch on the laboratory oven and allow it to
reach the set point temperature.
4.6 Apparatus Required For Calibration:Platinum

sensor (PRT) in the laboratory oven
as near as possible to the sensing

4.7.5 Correlate the readings observed with
the reference standards and apply corrections, if necessary.
