4.0 ACCOUNTABILITY

4.1 Head -Quality Control.

5.0 PROCEDURE

5.1 Procurement and handling of Thermometers

5.1.1 Procure the thermometers from standard agencies along with the calibration certificate traceable to NIST.

5.1.2 On receipt of thermometers a check shall be carried out of continuity of the mercury column, visibility of the scale, free from transportation damages & certificate for its adequacy.  

Remove from its original container carefully.

5.1.3 Allot the Code Number for each thermometer after receipt as specified below

Example: STH – 01- 06

Where STH – Standard Thermometers

               01 – Serial Number and

               06 – Year

5.1.4 Maintain a register for the inventory control of thermometers.

5.1.5 Record the below specified information as per the format for “Inventory Control Register of Thermometers”.

5.1.6 Hold the thermometer from its top.

5.1.7 Dip its mercury part into the liquid/solvent /sample, temperature of which is to be measure under specified condition if any.

5.1.8 Record the temperature by observing the height of mercury on the scale.

5.2 Storage of Thermometers

5.2.1 Store the thermometers, when not in use, in its original
container tightly closed in the designated place.

5.2.2 The calibration certificates are filed and preserved for a period of one year or till its validity.

5.3 Usage of thermometer
