Calibration of Drying Oven
3.3 TEMPERATURE CALIBRATION:
- Operate the instrument as per the SOP.
- Place a calibrated thermometer inside the constant temperature oven.
- Set the temperature at 50°C.
- After temperature is attained, measure the display temperature and standard thermometer temperature and note the readings in the given format.
- The observed temperature should be within ± 2°C of set temperature.
- Similarly set the temperature at 100°C and 150°C and repeat the above steps.
Temperature Calibration:-
| Set

| 100°C
|
98°C – 102°C | ||
| 150°C
|
