The NITRATO series features online analysers for the continuous monitoring of the nitrate nitrogen concentration (NO3-N). The advantages of the analyser include automatic calibration at regular intervals and the integrated sample pump, which makes an external feeding pump unnecessary in most cases. Available in three different housings: Standing with castors as NITRATO-LAB, wall-mounted as NITRATO-PRO or as NITRATO-FIX in a heated stainless steel cabinet for outdoor installation at the site of measurement.
