CS Instruments LD 450 - Leak detector

  • Meets the requirements of ASTM Int. E1002-05
  • Suitable for loud environments
  • 10 hour battery time

The LD 450 leak detector from CS instruments is ideal for spot detection of leaking compressed air, gas or vacuum systems.

The single battery powered, handheld device is able to detect the ultrasonic noise made from leaking fittings, loose screws or corroded pipe work. Small leaks cannot be heard by the human ear and larger leaks cannot be heard in loud environments.

The acoustic trumpet accessory which is the standard tool is ideal for detecting leaks at medium distances (0.2 – 6 meters). The laser integrated onto the acoustic trumpet allows for leaks to easily be pin pointed and marked.

The straightening tube accessory is for use to detect leaks at shorter distances (0 – 0.2 meters). This maybe required when there are many pipes or components which are close together.

The LD 450 also features a sound-proof headset for use in noisy and loud environments.
