response of electrode- using ph 4.0 7.0 and 9.0 read the
millivolt reading and make a graph with ph vs mv .graph
slope is between 90 percent to 110percent

burette . by selecting 1 ml 2ml 5 ml 10 ml and 20 ml
titrant is water. check the weight of water in each step
and 1 percent limit is allowed from the selected volume

temperature- compare with calibrated thermometer at minimum
4 intervals .1 percent error is allowed from the calibrater
thermometer.correlation coefficient of temperature graph
actual and set value should be greater than 0.9
