Portable Fluorometers

AlgaeChek Ultra
Modern Water’s portable fluorometer range includes the AlgaeChek™,AlgaeChek™ Ultra, BODChek™, PetroChek™ PAH, PetroChek™ BTEX.

The AlgaeChek™ fluorometer is a single parameter instrument while the AlgaeChek™ Ultra is a multiple parameteter portable fluorometer. These instruments provide a cost-effective solution to monitor the effects of organic pollution, identify potentially harmful cyanobacteria and turbidity.The AlgaeChek™ Ultra can be configured to detect up to three parameters.

Modern Water’s BODChek™ enables in-situ, real-time monitoring of Biological Oxygen Demand (BOD) within both natural water systems and water processing plants. The monitor detects fluorescent proteins that are inherent within sewage and slurry and provides an output in BOD equivalent units.

The PetroChek™ instrument enables in-situ, real-time monitoring of crude and refined hydrocarbons with both fresh and marine water systems. The monitor detects fluorescent poly aromatic hydrocarbons (PAHs) in crude oil and refined fuels and lubricants.

The specific compounds that can be detected by our fluorometer product range are identified in the table below.
