EM-500 | Inline Algae Sensor

DESCRIPTION:

The Pyxis EM-500 inline fluorometer probe (470 nm excitation and 675 nm emission) measures the in-vivo chlorophyll-a concentration of live algae cells present in water. Chlorophyll-a is the primary photosynthetic pigment of algae and fluoresces when exposed to proper wavelength. Chlorophyll-a measurement can be used to assess algal biomass of the bulk water in numerous industrial and process related applications. The fluidic and optical arrangement of the EM-500 probe is designed to overcome many shortcomings associated with other inline fluorometers by compensating for both color (as high as 10 ppm iron) and turbidity (as high as 150 NTU) present in the sample water. The EM-500 probe can come with a custom mounting tee which has two 3/4” female NPT or socket ports for plumbing into an existing 3/4” sample water line and can also be installed to a large tank or a body of water using the Pyxis Submersible Adapter (MA-102S). Additional mounting tee line sizes are available from Pyxis Lab. The EM-500 probe can be connected to any device that accepts an isolated or non-isolated 4-20mA input or RS-485 Modbus. The EM-500 probe has a short fluidic channel that can be easily cleaned as referenced in the Methods to Cleaning EM-500 Probe section of this manual. The EM-500 probe is pre-calibrated using a live algae sample. The fluorescence chlorophyll-a measurement is automatically compensated for sample color and turbidity interference. The EM-500 can be calibrated using a water sample with known chlorophyll-a concentration or a simulated 470 nm/675 nm (Excitation/Emission) fluorescent sample through the user-friendly uPyxis® App for both mobile devices and desktop. Diagnostic information (probe fouling, color or turbidity over range, failure modes) can be communicated to digital displays via Modbus RTU as well as via uPyxis® App. The EM-500 probe can be easily removed from the custom tee for cleaning without the need for any tools.
