Optical Nitrate Sensor

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

Optical nitrate sensor.

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. 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. This enables the sensor to fit in the existing exo bulkhead without need for any modification. 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. The nitravis is a reagentless optical based spectrophotometer built into a rugged corrosion resistant field probe for the iq sensornet system. The sensor is complemented by newly developed windows and mac based software for easy set up integration and in field.

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. 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.
