The TW series of weigh scales and data collectors record comprehensive weight and individual animal information. The TW-1 is an entry-level unit for collecting animal weights and tracking weight gain, while the TW-3 has advanced features for collecting and analysing additional data. Both models have rugged chassis, which have been designed to operate in difficult conditions. They are controlled via an intuitive touchscreen user interface, with a display that is easy to read in sunny weather conditions.
