LO-300® Laser scanning Oil Film Detector

Laser scanning Oil Film Detector

LO-300®

HORIBA LO-300® Laser scanning Oil Film Detector is a laser based Oil Pollution Analyser designed for on-line detection of oil leakage.

LO-300® Laser scanning Oil Film Detector, scans water surface with its built in laser to detect the presence of oil films on water surfaces and groundwaters. The LO-300® detects floating oil by sensing the difference in the intensity of reflection between water and oil. As compared with spotlight-based systems, the LO-300® adopted laser scanning method prevents interferences from water surface level fluctuation, and changes in distance between the water surface and the detector.

Laser scanning Oil Film Detector
LO-300®

LO-300® for high sensitivity detection of oil films on water surfaces.

Laser life time is four years The recommended maintenance cycle is four years. LO-300® is always watching the cumulative elapsed time of laser module, when it reaches to the limit, can display “exchange“ of a laser. The optical device in the main body has our original hanging structure, which assures vertical installation of the instrument even with a slight inclination of the detector, allowing easy installation work.	Detection distance from 0.3m to 4m LO-300® enables oil film detection under a fast sample flow with ripples to an extent, detection distance up to 4m between the detector and the water surface is possible. In case of the still-water surface, up to 6m is available. The laser scanner module rotates around the optical axis thus rejecting local light scattering by the wave ripple to detect the mean intensity of the reflection from the surface.
Variety of functions WARNING and ALARM, 2 alarm settings are available. LO-300® watches the cumulative elapsed time of laser module when it reaches certain level then requests the maintenance work.	Detection area setting is available The area detection function performs judgment by the rate of the oil film present on the detection area. Alarms caused by reasons other than oil leakage accident can be excluded.
Easily accessible monitor with 3.5 inch color LCD with touch panel Various operations are available such as reflection level diagnosis, instrumental error judgment, oil film detection etc. The LCD backlight is automatically turned off when there is no operation on the touch panel for 15 minutes or more. This function prolongs lifetime of LCD and saves energy.	Security Camera LO-300 with camera unit (option) enables to record the video when LO-300® detects the alarm and stores the image on the surface captured before and after alarm signal. The image with time stamp can validate that oil leakage is true or false.

Examples of installation

Laser scanning Oil Film Detector
LO-300®

LO-300® analyser provides an efficient interface with the LCD indicator of touch panel type to control and adjust various operating parameters such as status check, oil film detection and analysis settings. LO-300® Laser scanning Oil Film Detector is designed for installation at locations subject to oil leakage such as pits, clean water reservoirs, pools, drainage ditches, and manholes. It is suitable for early detection of oil leakage into rivers, seas and oceans and for prevention of outflow accidents and pollution events.
