TAS-Z1
Measure in the field.
Bring results into your project with confidence.
Tersus TAS-Z1 is a total station combining distance and angle measurements with data recording and stakeout functions. Dual control panels, an alphanumeric keypad and Bluetooth connectivity simplify field surveying and data transfer to the office.
- Angular measurement accuracy
- 2″
- Single-prism measurement range
- 5000 m¹
- Reflectorless measurement range
- 1000 m¹
- Dust and water protection
- IP55
¹ Measurement range is affected by target reflectivity, atmospheric conditions and setup. Single-prism, reflective-sheet and reflectorless values refer to different targets.
TECHNOLOGY AND PERFORMANCE
Details make a difference.
Fast distance measurement
With a single prism, fine measurement takes 0.3 seconds and tracking takes 0.1 seconds. Reflectorless measurement takes 0.3–3 seconds.
New EDM design
A 150 MHz modulation frequency, low-noise amplifier and optical signal separation form the basis of distance measurement.
30× telescope
The erect-image telescope provides a 45 mm effective objective aperture and a 1.2 m minimum focusing distance.
Dual panels, easy data entry
A backlit 24-key alphanumeric keypad and dual control panels support operation from either face.
Transfer via Bluetooth and USB
Transfer survey data through Bluetooth or USB and incorporate DAT, CSV and DXF outputs into your project workflow.
Road surveying and stakeout
Continue fieldwork with horizontal and vertical curve calculations, known-point coordinates and road stakeout functions.
APPLICATIONS
Technology that fits your project.
Mapping and land surveying
Collect angle, distance and coordinate data in the field.
Construction and stakeout
Set out design points on site and measure existing conditions.
Roads and infrastructure
Use road surveying, curve calculations and stakeout functions.
WORKFLOW
Three steps to operation.
Set up and orient
Complete setup with the laser plummet and levels, then orient using known points.
Measure and record
Select prism or reflectorless mode to record angles, distances and point data.
Transfer and evaluate
Retrieve data via Bluetooth or USB and continue the project using DAT, CSV or DXF outputs.
ppm denotes the distance-dependent error component. Runtime and measurement performance vary with field conditions and use.
