This manual describes how to use the testo Sensor LD leak detector.
The Testo Sensor LD is a handheld ultrasonic leakage detector designed to detect even the smallest, inaudible leaks in compressed air systems. It converts ultrasonic frequencies into audible sounds, allowing users to locate leaks with precision using headphones and an integrated laser pointer. The device includes accessories like an acoustic trumpet and focus tube to enhance detection accuracy. It operates on a rechargeable lithium-ion battery and features a 2" TFT color display for signal strength, volume, and battery level. Safety precautions are emphasized, including avoiding direct laser exposure to eyes and maintaining safe distances from energized parts.
