The Testo Sensor LD Pro Ultra Ultrasonic Leak Detector features a 3.5-inch touchscreen interface with direct display of leakage rates in liters per minute and annual costs in EUR. Automatic level adjustment optimizes sensitivity while filtering ambient noise, achieving minimum detection of 0.1 l/min at 6 bar pressure from 5 meters distance. The integrated camera captures visual documentation of leak locations for comprehensive record-keeping. Operating for 9 hours continuously on rechargeable lithium-ion batteries (4-hour charge time), the unit functions across 0 to 50°C with data logging via 2 GB SD memory card.

Data transfer to PC via USB interface enables report generation through the included Testo Leak software V2, specifically designed for ISO 50001 energy management audit compliance. Exported data includes leak images, timestamps, organizational identifiers, leakage rates with adjustable units, and annual cost projections with currency flexibility. The 30-microphone array provides significant time savings compared to conventional single-sensor detectors by enabling faster leak visualization and localization across industrial facilities.
