The TXSU is an adjustable, extra sensitive, high resolution Tensiometer, which has been developed specifically for the use in Substrate culture. The measurement range is between 0 and 250 hPa water potential, the Manometer shows MMM’s well approved self-explanatory color coding which has been specifically adapted to Substrates. Standard measurement depths (shaft length) are 15 and 20cm (other length available on request). The specialty of the TX Substrate Tensiometer is the front side zero correction of its gauge, eliminating issues with damaged manometers.
