Oil Detectors

Gestra oil detectors include the ORGS11-2 and OR52 series. The ORGS11-2 is an oil detection alarm that directly detects oil contamination primarily through an electrode-based design. The OR52 series, including the OR52/5 and OR52/6, consists of oil turbidity detectors based on optical turbidity measurement. When selecting a product, users should focus on key specifications such as the detection principle, Art.Nr., DN, and PN pressure rating to meet different on-site water quality monitoring and protection requirements.
