MEASURING PRINCIPLE
　　The measuring unit adopts the principle of infrared scattering which is used in the international field.
　　The sensors receive the light scattered andpenetrated by oil droplets in the oily water when the infrared transmit the flowing oily water and then the output signal is transmitted to CPU to be processed after being handled by amplifier, filter and A/D transmitter.

FEATURES
　　(1) High accuracy with advanced principle of infrared ray measurement and microprocessor technology
　　(2) The separation of control unit and measuring unit increases the stability and reliability of the instrument and also causes the convenience for maintenance and cleaning of the measuring unit.
　　(3) Most clear display of LCD shows the time,oil content, system running status all the time.
　　(4) The real-time data is saved automatically and can be read whenever you need.
　　(5) With the function of system failure alarm and self-checking.
