MoreThe Series130R instruments feature Sokkia's RED-tech EDM which provides outstanding range, speed and precision in reflectorless distance measurement. Narrow objects, walls, corners, and objects with small incident angles such as road manholes can be measured with pinpoint accuracy via the ultra narrow visible laser. It is also possible to make precise measurements through obstacles such as fences and tree branches. Accuracy is +/-(3 + 2 ppm x D) mm at a continuous measurement speed of 1.3 seconds.
The reflectorless measuring range of the standard Class 3R laser models reaches 350 meters (1,140 feet) (with Kodak Gray Card 90% reflective), and the range for a glass prism is up to 5,000 m (16,400 ft). The reflectorless range for Class 2 laser models (factory option) is up to 150 m (490 ft).
When the Series130R models are in the reflective sheet and prism modes, the Red-tech EDM automatically switches to a lower level laser output (maximum 0.22 mV) equivalent to the safer IEC Class 1/FDA Class I laser.
All models employ Sokkia's original absolute encoders for higher reliability in angle measurement. Angle accuracy for the SET1130R3 is 1" (0.3 mgon), 2" (0.6 mgon) for the SET2130R3, 3" (1 mgon) for the SET3130R3 and 5" (1.5 mgon) for the SET4130R3.
Approximately 10,000 data points in 10 job files can be stored in the internal memory. With a CompactFlash card unit (optional), data storage capacity is virtually unlimited.
The SF14 wireless keyboard, available as an optional accessory, allows for quick and easy entry of point names and coordinate values. Another optional feature is the Guide Light Unit, which greatly enhances efficiency when performing setting-out operations.
