Special Parameter Online Monitoring Instrument
In-water Oil (Animal and Vegetable Oil) Analyzer
product details

Product Model: OIL900


Measurement Principle


OIL900 In-water Oil (Animal and vegetable oil) analyzer is specially designed to measure oil (animal and vegetable oil) concentration in water. The instrument uses the infrared method to measure the concentration of oil molecules in water. The water sample is sent to the colorimetric pool after the pretreatment device, and the light source is irradiated to the oil molecules in the colorimetric pool in parallel to generate the absorption spectrum. The change of the absorbed light intensity is related to the oil content in the water, and the change of the light intensity is detected by the optical sensor and calculated by the control system.


Performance and Characteristics


Stable and Reliable Results

Advanced infrared measurement technology, on-line monitoring results are stable and reliable.

Long Maintenance Cycle

The water sample pretreatment device adopts maintenance-free design, which can ensure that the maintenance cycle of the pretreatment device exceeds half a year.

Increase of Service Life

The unique non-contact sampling eliminates the contamination of water samples to the sampling device and greatly extends the service life of the instrument.

Intelligent Data Processing

Automatic elimination of abnormal abrupt values caused by instrument failure makes the measurement data more accurate.

Online Monitoring Methods are Diversified

It can realize manual measurement at any time, automatic timing measurement, automatic periodic measurement and other measurement methods.

Multiple Signal Output

Data transmission has a variety of signal output such as RS232\RS485\4-20mA, and visually displays the oil concentration mg/L value.


No chemicals, consumables, no pollution, truly environmentally friendly.

Full Automatic Driverless System

Automatic and manual multi-point calibration, convenient for users to set flexible automatic calibration operation according to different water samples.
