ISE Ammonium Low Standard

The High and Low ISE standards are used to calibrate our Ammonium Ion-Selective Electrodes. User Manual - NH4-HST

The Go Direct Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of ammonium (NH4+) in aqueous samples. It connects via Bluetooth® wireless technology or via USB to your device. Specifications Range (mV): ±1000 mV Range (concentration): 1 to 18,000 mg/L (or ppm) Accuracy: ±10% of full scale (calibrated 1 to 100 mg/L) Interfering ions: K+, Li+, Na+, Cs+, Mg2+, Ca2+, Sr2+, Ba2+ pH range: 2–7 (no pH compensation) Temperature range: 0–40°C (no temperature compensation) 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) Connections:Wireless: Bluetooth Wired: USB What's included Go Direct ISE Amplifier attached to a Go Direct Ammonium Ion-Selective Electrode BNC Micro USB cable 30 mL bottle of High Standard solution with SDS (100 mg/L or 100 ppm NH4+ as N) 30 mL bottle of Low Standard solution with SDS (1 mg/L or 1 ppm NH4+ as N) Short-Term ISE Soaking Bottle User Manual - GDX-NH4

This module replaces the electrode membrane. Simply unscrew the old one and screw on the new one. The membrane of an Ammonium ISE electrode has a limited life span of one to two years, regardless of frequency of use. Do not order it until you need it, as it will age even when not in use.
