The APERA PION400-K Portable pH/mV/Potassium Ion Meter is a rugged, professional-grade solution designed for high-precision water quality analysis. Engineered for both laboratory accuracy and demanding field conditions, this IP57-rated waterproof meter provides a seamless experience for measuring pH, Ion concentration, ORP, and temperature.
The IndSen 2071M-K-TS ATC Potassium 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
Meter Features
- Intelligent Multi-Parameter Analysis — Effortlessly switch between pH, Ion concentration (pX, mol/L, ppm, mg/L), and mV modes with automatic electrode recognition
- Comprehensive Ion Support — Pre-configured for 15 commonly used ions (including Ca2+, NH4+ , NO3− , Cu2+, F−, K+, Na+, Cl-, Br-, I-, Cu2+, Ag+, S2-, Pb2+, Cd2+, Hg2+) with the ability to define custom "Ion X" parameters for specialized applications
- Ruggedized for the Field — Built to survive harsh environments with an IP57 waterproof and dustproof rating, all housed in a convenient carrying case for complete portability
- Precision Calibration — Features 1 to 3 point calibration with guided prompts and electrode slope display to ensure your data is always accurate
- User-Centric Design — Equipped with a large, backlit LCD, intuitive keypad operation, and intelligent self-diagnosis that alerts you to buffer errors or aging electrodes
- Complete Test Kit — comes with a 201T-S ATC pH electrode, IndSen 2071M-K-TS Potassium Ion Electrode, and all the necessary accessories for convenient in-field calibration and measurement.
