The BTS-812ERS Total Station is an easy-to-use measuring instrument with the port for SD memory card.It comes with a user friendly interface,and can realize reflectorless distance measurement,with a measuring range of 350m.The design of alphanumeric key,user defined function key and navigation key allows for convenient and fast Operation.In addition,only by pressing one function key,the total station can start measuring and recording the measurement data quickly.It also has the advantages of simple Operation,fast and accurate diatance measurement,so it is widely applied in various surveying and mapping work.
This total station can achieve real-time and two-way data transmission with the computer,also the graphical guidance for lofting through the use of online programmable technology.When connected with computer,it also allows for easy and fast upgrades for the application software.
1.The two pieces of high-capacity Ni-MH rechargeable batteries
support long time standby,thus making our total station suitable
for fieldwork.
2.The total station has a large internal memory that can store
50000 points of data,and can automatically record the data of
angle,distance,coordinate and so on.
3.It can be used for layout work,area computation,and accurate
measurement of coordinate,suspension height
measurement,resection,subtense,eccentricity,angle measurement,etc.
4.The application of various reflective film and targets makes the
measurement process conveient and flexible.This instrument can also
be equipped with the laser plummet and slide tribrach for option.
