The ZN22-T-IP is a point dendrometer with a sealed potentiometer (IP54) for operation in very wet conditions. The frame is made of one piece of carbon fiber (CFK) and is consequently combined with stainless steel elements (rods and nuts) in order to minimize the temperature sensitivity. The ZN22-T-IP is the successor of the ZN11-T-IP and has a waterproof welded cable (without connector) on the sensor. Applicable for tree stems >7 cm in diameter. The frame offers the possibility to hold a second potentiometer.
