TOMST S.r.o. products

Potentiometer based point dendrometer brings the possibility of precise automatic measurement of the stem diameter changes < 1 µm in user defined intervals. Also, the dendrometer is able to measure air temperature, thanks to the thermocouple placed in the bottom part of the body. Its robust construction and high capacity lithium battery ensure that it is resistant to all kinds of extreme conditions.

Standard unit is measuring temperature in 3 different levels and measuring the soil moisture as well. The unit is installed into the ground and the reading probe of the unit is above the ground level. It is mainly used for measuring soil moisture and temperature in a depth of -6, +2 and +15cm.

The TMS extreme is the same size as the TMS Standard (29 cm) although slightly heavier at 118 g. The placement of the temperature and soil moisture sensors is likewise identical, which allows for uncomplicated data comparison. Further improvements are hidden within the sensor. The battery included has a capacity of 3500mAh, which is a 30% increase compared to the TMS Standard. This translates into a longer lifetime, expected approx. 14 years as well as a wider temperature range of measurement. Moreover, the device is filled with epoxy to the very top, making it heavier but also even more durable.
