ROW ATEX EXD oil spill detector is designed to detect oil contamination in hazardous areas where ignitable concentrations of flammable gases, vapours or mists often exist.

ROW ATEX EXD Oil Detector is encased in a flame-proof (explosion-proof) DNV-certified enclosure made of 316 stainless steel, which is acid and corrosion resistant, making it ideal for the toughest environments.

IP68-certified non-contact Ex D Oil Detector, using UV fluorescence method, the highest rated in the market.

Outstanding detection range of 8m — twice the distance compared to similar products on the market.

Calibrated advanced software algorithms to detect oil down to a single micron layer while minimising false alarms.

ROW ATEX EXD Oil Detector can be installed within a network of LDI ROWs and connect seamlessly with third party telemetry options using RS485, 4-20mA PLC, or a simple alarm relay.

The best-in-class ROW ATEX EXD is now ATEX and IECEx-certified, ensuring world-class performance and reliability perfect for your situation. View certificates here.

ROW Light Fraction is an optional, well-sought-after oil detector that’s specially designed for detecting light, medium and heavy oil fractions across various applications and industries. It provides top-notch performance, making it the most reliable oil detection you can find on the market.
