Enviro T2

Enviro-T2™ is an accurate, single-channel fluorometer that easily integrates with data collection systems providing a 4 – 20 mA output proportional to the fluorescence from chlorophyll in water. When configured with a Blue Excitation LED, Enviro-T2 detects fluorescence from all algal groups; when configured with a Red Excitation LED, it has maximized sensitivity for better detection of Cyanobacteria. Enviro-T2 uses solid-state optoelectronics making it a reliable, high performance, rugged continuous sampling device. Instrument maintenance or inspection is greatly simplified with a quick one-step disconnect. Factory-calibrated and requiring minimal installation effort, simply plumb the Enviro-T2 in-line with your online monitoring systems, connect the output of your controller or data logger, and supply power to estimate algal abundance as a biological parameter for your monitoring program.
