ORP Sensor S80 Lab & Portable The HYDRA Nitrate Sensor is

The HYDRA Nitrate Sensor is designed to monitor the nitrification process directly in the aeration basin or clarifier of a Wastewater Treatment Plant

a 10 % low error will occur at pH13 and 50% low error will occur at pH 12

they have produced a higher output in clean water applications

500 ml bottle 100 ppm (mg/l) Cupric ion solution with ISA (ionic strength adjuster)

The HYDRA DS Ammonium Sensor is designed to monitor the nutrient load (NH4+) directly in the aeration basin of a Wastewater Treatment Plant

ORP Sensor S80 Lab & Portable The HYDRA Nitrate Sensor isThe Model S80 Intelligent Sensors are a complete line of liquid analytical sensors including pH, ORP, Specific Ion, Dissolved Oxygen, Conductivity and Resistivity. The S80 sensors have two Universal Sensor Designs; Insertion Submersion or Valve Retractable with flared end to prevent blow out. The standard S80 sensors have 316 Stainless Steel housings although various materials of construction are available to maximize sensor performance while
