• A simple method of measuring the volume change of a specimen by means of a low capacity differential pressure transducer (LC-DPT) has been used for laboratory tests. Several kinds of error in this method evaluated by calibrating this method with another automated volume change measuring method by means of an electronic balance are described. It was found that if water flows in the tube located between the burette and the LC-DPT the tube friction associated with the flow of water in the system can induce the largest amount of error among other kinds of error. It was also found that this kind of error described above can be kept to a very small value by using a proper connection method of joints and tube.
