Advanced device recognizedthroughout the world.

The principle of measurement using ourunique technology is preeminent above
others.
Measuring method
The FOCAS-1800 using a full optical continuous measuring method* cansurely grasp changes of oil concentration every moment while providing avery quick measurement response.

Since our company was established in 1969, we have been developing environment
monitoring devices and many measuring instruments and sending out them into theindustrial world to make a contribution for environmental protection.
In these days in which environmental pollution is gradually advancing on a worldwide
scale, the whole world is tightening the environmental protection and monitoring onstricter standards.
This advanced device FOCAS-1800 has been researched and developed by using theaccumulated technology that was highly appraised as a result of sending out the Oil
Concentration Detector FOCAS 3 Series in the past. The FOCAS-1800 having uniquehigh performance that was expected by users has been wining unstinted praise bothin Japan and in the world since it was released.

＊The light coming from optical elements is received by multiple optical elements. Then, acomplicated analysis about changes of oil type or concentration and differences of pattern
due to mixed foreign substances can be made by CPU and software in an instant throughcalculation.

pressure which is matched to the operation of an oil separator or pump.
● The automatic washing function of the detection unit can reducetroublesome manual washing work, (Option)● An error code indication provided at occurrence of a device fault and astain indication of the detection unit facilitate maintenance andinspection. The product has a high-maintainability structure.
● Operation records such as trouble alarms can be saved in a memory
card and confirmed as required.
● The product can measure only the oil concentration and is not affectedby SS content(floating turbidity substance other than oil content) anda detergent.
● For alarms, a double safety method is used. When the oil concentration
is 15 ppm or more, an oil alarm is output. When sample water isdefective or the instrument is defective, a trouble alarm is output.
