The Pyxis HM-900 is a handheld portable fluorometer that measures the concentration of multiple oils in water (Marine-Offshore Oil, #1 Diesel/Kerosene, and Heavy Fuel Oil), using an LED-sourced UV fluorescence methodology at 365nm/410nm with automatic dual-channel range selection.

The HM-900 offers two extraction methods: Hexane Extraction and a Pyxis Lab prepared non-toxic, non-flammable solvent, supporting both 24mm and 16mm sample vials. Three default built-in calibration curves are provided for the primary oil classes, plus up to 7 customisable user-defined curves. A direct-read method is also available for dissolved or lightly emulsified oil without extraction.

Typical applications:

• Heat exchanger leakage detection
• Oil tank leakage detection
• Intake water monitoring (UF & RO feedwater)
• Re-injection water monitoring
• Industrial wastewater monitoring
• Marine discharge monitoring
• Plant run-off / storm water monitoring
