Pentax W822NX total station


Item specifics
Brand Name: Pentax
Model Number: W822NX
Accuracy: 2"
Color: Red
W-800 SERIES FEATURES:
The use of Windows CE. NET makes it possible to replace application software and access the Internet using a communication modem card. High resolution (VGA) LCD display provides highly clear graphic display close to that of a PC, making the W-800 series a new generation total station.
Both total station and data collector need to be brought to the survey site and by operating the both instruments, survey data are taken, stored and processed. The W-800 series can do all that alone.
The storage and transfer of large-size data and flexible data communication are possible with the availability of 4 kinds of standard interface, i. e. R-232C, USB, CF Card slot and SD card slot.
