  • 30 mL bottle of Low Standard solution with SDS (1 mg/L NO₃^–)
  • Short-Term ISE Soaking Bottle
• Nitrate concentration, which can be increased by acidic rainfall, fertilizer runoff from fields, and plant or animal decay or waste, is an important parameter in nearly all water quality studies. The Go Direct Nitrate Ion-Selective Electrode is used to wirelessly determine the concentration of the nitrate ion in a water sample. These levels can be measured as mV or mg/L.
• The versatile BNC connector allows students to easily replace the electrode when it expires or becomes damaged. You need only replace the electrode and not the entire sensor—lowering your overall equipment costs.
• The Go Direct Nitrate Ion-Selective Electrode has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module and replace it with a new one.
