Catalog No.	Temperature Range (Metric)
S39719	0°C to 40°C

Catalog No. S39719 Supplier Vernier™ Supplier No. GDXNH4

Description

Vernier™ Go Direct™ Ammonium Ion-Selective Electrode can be used to measure the concentration of ammonium in aqueous samples.

• Range (concentration): 1 to 18,000 mg/L (or ppm)
• pH range: 2 to 7 (no pH compensation)
• Interfering ions: K⁺, Li⁺, Na⁺, Cs⁺, Mg²⁺, Ca²⁺, Sr²⁺, Ba²⁺ 
• Electrode slope: 55 ±3 mV/decade at 25°C
• Electrode resistance: 0.1 to 5 MΩ
• Minimum sample size: must be submerged 2.8 cm (1.1 in.)
• Use the Go Direct Ammonium Ion-Selective Electrode to wirelessly measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels, if sample solutions are acidified to convert NH₃ to NH₄⁺.
• 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 Ammonium 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.
