Thông tin sản phẩm


The Fellow Kogyo FOCAS-2000 Bilge Alarm using a full optical continuous measuring method can sure grasp changes of oil concentration every moment while providing a very quick measurement response.

The light coming from optical elements is received by multiple optical elements. Then, a complicated 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 through calculation.


Product Features:

  • This product adopts an automatic operation method using sample water pressure which is matched to the operation of an oil separator or pump.
  • The automatic washing function of the detection unit can reduce troublesome manual washing work.
  • An error code indication provided at occurrence of a device fault and a stain indication of the detection unit facilitates maintenance and inspection. The product has a high-maintainability structure.
  • Operation records such as trouble alarms can be saved in a memory card and confirmed card and confirmed as required.
  • For alarms, a double safety method is used. When the oil concentration is 15 ppm or more, and when sample water is defective or the instrument is defective, an alarm is output.
  • Replacement of detecting part (sensor unit) separately sold can be accepted as the completion of every five years’ calibration.
