The R20 range is composed of 3 versions, the R20 1000 m model with 2″ angular accuracy, the R20 1000 m model with 1″ angular accuracy and the R20 600 m model with 2″ angular accuracy.
STT402L offers the opportunity to challenge high-precision monitoring and engineering works. Thanks to its absolute encoder, angle measurements are saved when STT402L is switched off. Low power consumption gives more than 80 hours working time.
