The DADI DTM752R is a 2″ reflectorless total station designed for surveying, construction layout and field measurement. It provides a reflectorless measuring range of up to 600 m and a single-prism range of up to 3 km, with reflectorless distance accuracy of 3 mm + 2 ppm. Compared with the DTM652R, the DTM752R features a dual-axis liquid-electric compensator with a ±3′ compensation range and uses DADI SURVEY PRO-S onboard software. Bluetooth communication and integrated surveying programs support efficient data collection and field operation.
The DADI DTM-752R is a 2″ reflectorless total station designed for construction layout, engineering surveying and field measurement. It provides reflectorless distance measurement up to 600 m, single-prism measurement up to 3,000 m and triple-prism measurement up to 5,000 m.
The DTM-752R combines 2″ angular accuracy with a dual-axis liquid-electric compensator and DADI SURVEY PRO-S onboard software. Bluetooth, RS-232C communication, SD card support and internal data storage provide practical field data management without a USB interface.


The DTM-752R measures up to 600 m without a prism, up to 3,000 m with a single prism and up to 5,000 m with a triple-prism configuration under suitable measuring conditions.
The absolute-encoder angle measurement system provides 2″ angular accuracy for construction layout, engineering surveying and other precision field measurement tasks.
The liquid-electric dual-axis compensator operates within a ±3′ compensation range and monitors instrument inclination in two axes during measurement.
The DTM-752R uses DADI SURVEY PRO-S onboard surveying software for field measurement, data management and surveying calculations.
Integrated Bluetooth, RS-232C communication, SD card support and internal storage for approximately 16,000 points provide multiple options for field data transfer and storage. The DTM-752R does not include a USB interface.

Angle and distance measurement for building layout, structural positioning and construction control.
Field measurement for civil engineering, infrastructure and general surveying projects.
Coordinate and boundary measurement using reflectorless or prism-based EDM measurement.
Measurement of building surfaces and other points where placing a prism is difficult or impractical.
The DTM-752R provides reflectorless distance measurement up to 600 m under suitable measuring conditions.
The specified angular measurement accuracy is 2 arcseconds.
The two models share the same main angle, EDM and optical specifications. The DTM-752R uses dual-axis compensation and DADI SURVEY PRO-S software, while the DTM-652R uses single-axis compensation and DADI-Pro1. The DTM-752R does not include the USB interface available on the DTM-652R.
Yes. The DTM-752R supports integrated Bluetooth communication for wireless field data transfer.
No. The DTM-752R does not include a USB interface. It supports Bluetooth, RS-232C and SD card-based data handling.
The DTM-752R uses DADI SURVEY PRO-S onboard surveying software.
