General Information
2.2 Product overview
The NITRATAX plus sc sensor ( Figure 2 , item 1 ) measures the nitrate concentration up to
100 mg/L N directly immersed in the medium. Use the sensor without the need for
pumping and conditioning in activated sludge tanks in municipal sewage treatment plants,
surface water, untreated water and treated drinking water. The system can also be used
for checking the outlet on waste water treatment plants.
The NITRATAX eco sc ( Figure 2 , item 2 ) measures the nitrate concentration up to
20 mg/L N directly immersed in the medium. Use the sensor without the need for pumping
and conditioning in activated sludge tanks in municipal sewage treatment plants.
The NITRATAX clear sc ( Figure 2 , item 3 ) measures the nitrate concentration up to
20 mg/L N directly immersed in the medium. Use the sensor without the need for pumping
and conditioning in clear media such as surface water, treated drinking water and sewage
treatment plant outlets.
Note: The flow-through units of the high precision NITRATAX plus sc and the NITRATAX clear sc
sensors are used wherever direct measurement in the medium is not possible for structural reasons,
or the medium load makes it necessary to measure a filtered sample (very high TS content, sewage
treatment plant inlet, waste dump leachate, etc.).
