Optical Nitrate Sensor

The uv approach offers several advantages compared to wet chemical nitrate sensors and ion selective electrodes table 1.

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. Suna provides real time chemical free nitrate calculations in coastal and freshwater environments using satlantic s advanced uv absorption technology. This enables the sensor to fit in the existing exo bulkhead without need for any modification. All exo probe guards and flow cells still work with exo nitraled.

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. However uv nitrate sensors from individual manufacturers differ in several.

Featuring a high degree of accuracy due to direct uv measurement without cross sensitivities nitratax sc nitrate sensors are ideally suited to statutory limit value monitoring. 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.
