LP402L Laser Digital Theodolite
Telescope laser emitting system provides a visible laser beam which can be seen up to 150 metres away outside through eyepiece in daylight(LP400 series)
Laser pointer brightness and focus adjustable(LP400 series)
Laser emitting system is integrated with telescope, resistant to dust, rain and other harsh elements(LP400 series)
With absolute encoder, angle measurements can be saved when power off
Compact design with wide LCD display facilitates numerical reading and operation
Minimum reading:1″/5″/10″ or 0.2mgon/1mgon/2mgon
Repeated angle program carries out continuous measuring and average calculating to get high-accuracy angle value
Rechargeable battery and AA battery are available
Lower power consumption, longer working time with one battery
