TROTEC SL800 Ultrasonic Leak Detector - Air/Gas/Vapour Leak Detection

SL 800 Ultrasonic Leak Detector – TROTEC

The SL 800 is a professional device specifically designed to identify leaks and sealing defects within compressed air, gas, steam, or vacuum systems. Its operation relies on capturing the ultrasound produced by fluid escape or mechanical wear, signals inaudible to the human ear but converted into usable audible and visual indications.

A technology that is both precise and adaptable

The SL800R probe picks up ultrasonic vibrations and translates them into audio and light signals. The operator perceives this information through an insulating headset while consulting the intensity on a 10-segment LED bargraph. This visual and auditory duality ensures reliable diagnostics, even in noisy environments. For non-pressurized systems such as tanks, climate chambers, or technical enclosures, the SL800T transmitter complements the equipment by generating artificial ultrasound to verify tightness.

Application areas of the SL800

With the structure-borne noise probe:

Preventive monitoring of ball bearings, roller bearings, or plain bearings

Detection of cavitation within centrifugal pumps

Control of proper functioning of steam traps

Verification of valve and tap tightness
