The high performance ammonia ion selective electrode (ISE) allows fast, simple, economical, and accurate measurements of dissolved ammonia in aqueous solutions.

• Response time of 1 minute in sample concentrations of 1 ppm and higher; fast results make it easy to combine functionality with autosamplers
• Keying feature on the electrode body prevents membrane from twisting or breaking during assembly
• Choice of preassembled outer body with membrane cap or loose membranes
• New wastewater applications developed using known addition and direct measurement techniques
• EPA-compliant method
• Waterproof BNC connector

This gas sensing electrode can also be used to measure the ammonium ion after conversion to ammonia or to measure organic nitrogen after Kjeldahl digestion of the sample. Sample colour and turbidity do not affect the measurement and samples do not need to be distilled. Almost all anions, cations and dissolved species, other than volatile amines, do not interfere.
