| Radius Dendrometer (Type DR) Highly precise ● Widely applicable in different measurements (radius, diameter, circumference, stem length, fruit diameter) ● Extremely light (13 g), Less strain on plants ● No power consumption, and with our ulogger standing-alone can measure for up to 2 years ● Suitable for any outdoor conditions ● No calibration required, with a direct μm output ● Proven track record of more than 10 years in use under outdoor conditions ● Least maintenance requirements Changes occur in plant tissues as a result of growth and water content. Diurnal fluctuations reflect changes in tissue water content while seasonal dynamics are attributed to long-term increases due to growth. It has long been in the interest of plant scientists to design precise and appropriate ins truments to monitor such changes in plants in a precise time scale and to correlate them with environmental changes for accurate interpretation of plant responses to the environment. Techniques are currently available for accurate monitoring of physical environmental parameters, but to obtain accurate corresponding data for plant responses has been difficult. Quantitative measurements such as yield, tree ring width, etc. are cumulative results of effects of various environmental factors integrated over a complete growth season, e.g. one year and therefore, lacks precision (i .e. which environmental factor, at what time and in what in-tensity it affects plant growth). To study relationships between environment and plants, there is need for precise, simul-taneous data on plant responses and environmental variables that influence these responses. Dendrometers are ideal tools for meeting such demands. The Ecomatik Dendrometers (patents pending) are highly precise instruments for continuous monitoring of radial and vertical changes of plant tissues e.g. stems, fruits, leaves etc..
