Mineral oil in water can cause water pollution and affect the growth of aquatic animals and plants. It is a necessary test item for surface water and wastewater discharge from multiple industries.

At present, the commonly used standard infrared spectrophotometry method (HJ637-2012) for oil detection in water in China requires the use of carbon tetrachloride as an extractant, which is highly toxic to the human body and seriously pollutes the environment, limiting the use of oil detection in water. The US Environmental Protection Agency's EPA Method 1664 recommends n-hexane, and China's Ministry of Environmental Protection has also initiated a project to revise existing standards.

The HM-500 series online water oil probe adopts ultraviolet fluorescence detection technology, with high sensitivity, and can detect oil content in water online. The probe can be assembled into a customized tee, which has two three-quarters inch (DN20) NPT internal threaded openings for easy installation into the same three-quarters inch (DN20) water intake circuit. The online probe has an internally isolated 4-20mA current output and can be connected to any controller that supports isolated or non isolated 4-20mA inputs; The design of the HM-500 series online oil probe in water makes it very easy to clean, which can prevent the accumulation of impurities from affecting the measurement.

Typical applications:

Surface water such as Rivers and Lakes, environmental monitoring, industrial sewage and wastewater such as petroleum and petrochemical, thermal power plants, steel manufacturing, oilfield reinjection water monitoring, condensate water, circulating water detection, pipeline oil leakage trend monitoring and alarm.

Product features:

• Advanced optical monitoring method, no reagents, no dilution, instant results, long-term stable operation
• Pollution resistant design: Embedded quartz tube flow channel design, greatly reducing the need for cleaning and maintenance
• Oil content in water can be calibrated based on sample concentration
• Built in transmitter, no need for preamplifier or header, directly outputs RS485 or 4-20mA isolated signal, more stable and accurate long-distance transmission
• Calibration, data recording, and diagnosis can be performed on personal computers or smartphones through Bluetooth/USB adapters
• Before leaving the factory, the probe undergoes pressure aging testing and pre calibration to ensure stability and reliability
• Standard IP67 aviation connector, can be directly connected to Pyxis UC-100/UC-1000 universal controller
