The IndSen 2071M-K-TS ATC Ammonium Ion Selective Electrode is a high-performance sensor designed for the direct measurement of potassium ion concentration (K+) in aqueous solutions. Engineered with proprietary Ultra-firm PVC Membrane technology and Long-life reference system, this electrode overcomes the limitations of conventional sensors, providing unmatched durability and rapid response for demanding applications like industrial wastewater treatment, environmental monitoring, fertilizer management, and academic research.
Potassium ISE Features
- Ultra-Firm PVC Membrane Technology: Utilizes a solid, non-volatile electrolyte and an active ion carrier reservoir that enhances mechanical strength and extends electrode life by 2-3 times compared to ordinary PVC electrodes
- Rapid & Stable Measurements: Delivers a 90% response in just 10 seconds, with a stabilization time of only 2 minutes after immersion
- Wide Dynamic Range: Capable of detecting concentrations from 0.039 to 3910 mg/L (ppm), suitable for everything from clean drinking water to concentrated industrial samples
- Temperature Integrated Sensing: Simultaneously measures ammonium concentration and temperature, with a 30KΩ NTC thermistor for automatic temperature compensation
- Advanced Double-Junction Reference: Features a long-life reference system with a silver-ion-free gel electrolyte, effectively preventing junction clogging and ensuring long-term potential stability.
- Rugged Industrial Build: Rated IP67 waterproof and featuring a robust 16 mm housing, it is designed to withstand harsh measurement conditions in the field or even long-term monitoring.
- Efficient Dry Storage: Unlike liquid-filled sensors, this electrode can be stored dry when not in use, requiring only a brief 5–10 minute pre-conditioning soak before measurement
Item Specifications Measurement Range 6 – 0 pK， 10-6 – 1 mol/L， 0.039 – 39000 mg/L（ppm） Slope 54 ± 5 mV (@ 25 °C) Operating Temperature Range 5 ~ 50 °C Solution pH Range 1.0 ~ 9 pH Electrode Resistance 2 ~ 10 MΩ Reference Solutions ReferenceⅠ: 0.1mol/L CH3COOLi gel，Reference Ⅱ：3.5mol/L KCl gel Temperature Sensor 30 kΩ NTC Response Time 10 seconds (90% response) Stabilization Time 2 minutes after immersion Stability < 8 mV / 24 h (< 1000 ppm) Ion Selectivity Coefficients K+: 1×10−1; Na+: 1.6×10−3; Ca2+: 6×10−5; Li+: 3×10−5 Waterproof Rating IP67 Dimensions Measuring tip: Ø16 × 120 mm; Electrode cap: Ø20 × 65 mm Cable Length 1 meter Connector 8-pin We warrant this electrode to be free from defects in material and workmanship and agree to repair or replace free of charge, at the option of APERA INSTRUMENTS, LLC, any malfunctioned or damaged product attributable to the responsibility of APERA INSTRUMENTS, LLC for a period of SIX MONTHS from the delivery.
