Walchem ST-587 Pyxis Inline PTSA & Turbidity Sensor, 0-500 ppb PTSA / 0-200 NTU, UPVC

The Pyxis ST-587 Series inline fluorometer & turbidimeter measure the concentration of PTSA and Turbidity in water. They utilize both LED UV and Warm White light sources. PTSA is commonly used as a fluorescent tracer in cooling and process water treatment. UPVC version of the sensor platform are better suited for application pressures below (100psi / 6.9 Bar).

The ST-587 Series sensors can be connected to any device that accepts an isolated or non-isolated 4-20mA input or RS-485 MODBUS input. The ST-587 sensor has extra photo-electric components that measure the color and turbidity of the sample water. This extra feature allows automatic color and turbidity compensation to eliminate interference commonly experienced in real world applications. As well as in-situ sensor cleanliness diagnostic data. The ST-587 Series sensors have a short fluidic channel, are very easy to clean and are uniquely designed to overcome issues associated with other fluorometers that have a distal (flat) sensor surface or a long, narrow fluidic cell.
