The construction adjustments of tensiometer are described. The designed tensiometer is sufficiently accurate and sensitive. The most important adjustment is a smaller volume of connection pipe, as well as its minimum length. This adjustment significantly decreases the temperature sensitivity of the tensiometer. In comparison with foreign products, there is a slightly higher volume of water in the designed tensiometer. The effect of temperature as far as measuring in field conditions is concerned is to be insignificant. The tensiometer is constructed from parts produced in Czechoslovakia with the predominant part located under the soil surface. This, together with the minimum internal volume of the tensiometer, causes an insignificant effect of temperature; also sensitivity and speed of reaction to the changes of suction pressure do meet the requirements.
