Optical Nitrate Sensor

Now licensed and marketed by sea bird scientific the uv absorption deconvolution method is the technol ogy behind the suna optical nitrate sensor allowing researchers and managers to get reli able nitrate concentration measurements without the limitations of traditional wet chemistry.

Optical nitrate sensor.

The nitravis is a reagentless optical based spectrophotometer built into a rugged corrosion resistant field probe for the iq sensornet system. Hach s nitratax sc family includes digital optical probes for the high precision determination of nitrate concentration directly in the medium. Nitrate at a specific wavelength is measured by a photometer and converted to a nitrate concentration. Suna provides real time chemical free nitrate calculations in coastal and freshwater environments using satlantic s advanced uv absorption technology.

With recent advances in uv led technology ysi has produced an optical nitrate sensor in a compact form factor that fits in the palm of your hand. The sensor is complemented by newly developed windows and mac based software for easy set up integration and in field. This enables the sensor to fit in the existing exo bulkhead without need for any modification. The uv approach offers several advantages compared to wet chemical nitrate sensors and ion selective electrodes table 1.

The nitravis probe scans 256 wavelengths per measurement between 200 and 720 nm to provide the most accurate nitrate and tss measurements with precise compensation for interferences such as turbidity. However uv nitrate sensors from individual manufacturers differ in several.
