Thermo Scientific™ Orion™ Nitrate Ion Selective Electrodes provide a fast, accurate, and cost-effective method for measuring free nitrate ions (NO₃⁻) in water, wastewater, environmental, and food samples. These electrodes are ideal for laboratories that require NIST-traceable measurements and regulatory compliance, including Standard Methods SM 4500-NO₃⁻ D and Orion Method 601.
Available in combination electrode (9707BNWP), the Orion nitrate electrodes feature the Sure-Flow™ junction to prevent clogging and maintain stable measurements. The combination electrode includes an integrated sensing and reference element.
