The STM Soil Tension Meter is a complete system for collecting and storing data from up to five Pressure Transducers in the field or laboratory. The STM is equipped with an internal battery which provides power to the Data Logger as well as the transducer attached to the Infiltrometer.
11.6” or larger and a default screen resolution of 1366 x 768 (the vertical height of 768 being most important otherwise you can't see the bottom of the software). ICT International Solutions for soil, plant & environmental monitoring...
Connecting a Power Supply to the Instrument (pages 6 to 11). The STM has an internal battery which can supply up to 6 hours of continuous use. The STM can be used in the field without an external power supply for at least 6 hours. It is recommended to charge the battery overnight with the CH7 power supply for use in the field the next day.
