Professional Leak Analysis and Energy Loss Assessment
Leak Quantification and Savings Calculation
Displays leak rates (l/min or cfm) and calculates estimated annual losses or potential savings in the selected currency, supporting investment decisions.
Integrated Camera for Documentation
The built-in camera enables leak photography and documentation directly on site. Images are stored together with all relevant leak information.
Auto Level for Stable Detection
The Auto Level function automatically adjusts sensitivity according to environmental conditions and effectively minimizes background noise for more reliable measurements.
ISO 50001 Reporting
The software enables creation of professional ISO 50001-compliant reports for energy audits and leak analysis.
Long Battery Runtime
Up to approximately 9 hours of continuous operation allows a full day of field work without frequent recharging.
Additional Sensors (LD 510 Only)
The LD 510 model includes a universal input for additional CS Instruments sensors such as pressure, flow, temperature, or dew point sensors, significantly expanding its capabilities.
Easy Data Transfer and Analysis
Leak data can be transferred to a computer via USB for detailed analysis and reporting.
