Professional After-Sales Service, Repair & ISO/IEC 17025 Calibration

At A & A Lazer-Tek (Pvt) Ltd, we offer top-tier after-sales service and technical support for all brands of line lasers and surveying instruments, ensuring efficient surveying instruments maintenance. Operating from our dedicated laboratory in Sri Lanka, we help your high-precision alignment and geospatial equipment maintain peak field performance, structural reliability, and minimal project downtime, essential for effective construction equipment service.

Comprehensive Repair & Servicing 

Our technical team conducts thorough multi-point pre-alignment inspections and complete mechanical overhauls for all industry brands, ensuring the highest standards of surveying instruments maintenance.

Optomechanical Cleaning

Deep servicing of eyepieces, objective lenses, and internal optics.

Structural Audits

Inspection of foot screws, baseplates, and leveling bubbles.

Component Testing

Functional evaluation of automatic magnetic damping compensators and self-leveling pendulums.

Advanced Multi-Axis Calibration Infrastructure

We employ advanced Multi-Collimator Systems and micro-precision Linear Baseline Laser Interferometers to eliminate focal errors and accurately isolate systematic alignment deviations.

Our standardized diagnostic procedures accommodate a wide variety of equipment types.

Surveying Instruments

Comprehensive testing of Total Stations (Hz/V collimation, tilting axis, plummets), Theodolites (angular measurements), and Automatic Levels (compensator verification) solidifies our commitment to effective surveying instruments maintenance.

Multi-Line Lasers

Planar, vertical, orthogonal 90-degree intersection, and full 360-degree cross-line leveling validation for multi-line green laser diodes.

Distance Meters & GNSS

Precision verification of optoelectronic time-of-flight shifting against stable physical benchmarks and GNSS antenna phase center variations.

Our processes are rooted in strict environmental monitoring, independent quality controls, and standardized measurement uncertainty budgets. Every serviced unit comes with a formal Certificate of Calibration tied directly to its brand, model, and serial number.

All physical parameters are fully traceable to international standards, providing an expanded uncertainty confidence profile of 95% to 98%. This guarantees your instruments meet stringent legal, commercial, and regulatory compliance requirements before returning to the field, ensuring top-notch performance in all surveying activities.
