An inexpensive, easily constructed pressure chamber is described which can be used for estimating xylem water tension. Such a chamber apparatus can be assembled for as little as $60 and can measure tensions greater than–100 bars. The static testing of the finished chamber with either water or oil is necessary before it can be used.
