Overview
The TimePower TP-130 Online Sodium Ion Monitor is a high-stability, multi-channel potentiometric analyzer engineered for continuous, real-time measurement of sodium ion activity (pNa), pH, and temperature in aqueous process streams. It operates on the Nernst principle, utilizing ion-selective electrode (ISE) technology to quantify sodium concentration across an exceptionally wide dynamic range—from 0.01 µg/L (pNa 9.36) to 23.0 g/L (pNa 0.00). Designed for demanding industrial environments, the system delivers trace-level sensitivity essential for boiler feedwater monitoring in thermal power plants, ultra-pure water validation in semiconductor and pharmaceutical manufacturing, and effluent compliance tracking in chemical and metallurgical facilities. Its architecture integrates electrochemical sensing with embedded microcontroller-based signal conditioning, enabling robust performance under variable flow (10–40 L/h), temperature (0–60 °C), and particulate load (<5 µm solids, no colloids).
Key Features
- Configurable 1–4 independent measurement channels—optimized for cost-effective scalability in multi-point monitoring applications.
- High-fidelity sodium composite ISE and triple-junction pH electrode with integrated PT1000 temperature sensor—ensuring simultaneous, cross-compensated pNa/pH/T measurements.
- 24-bit analog-to-digital conversion with auto-zeroing circuitry—achieving measurement accuracy of ±0.03 pNa or ±3 µg/L (whichever is greater) and long-term stability <±0.02 pNa/24 h.
- Industrial-grade embedded MCU platform with low-power consumption (10 years upon power loss) via non-volatile flash memory.
- 7-inch color TFT capacitive touchscreen with intuitive Chinese-language HMI—supporting rapid menu navigation, calibration logging, and alarm configuration without external software.
- Flexible analog output options: isolated 0–20 mA, 4–20 mA, or 0–10 mA (load ≤750 Ω); programmable relay outputs per channel for high/low limit, flow failure, and maintenance alerts.
- Front-panel cutout mounting (670 × 410 mm) with compact cabinet footprint (460 × 280 × 720 mm) and 22 kg weight—designed for integration into control rooms, skids, or field instrument enclosures.
Sample Compatibility & Compliance
The TP-130 is validated for use with low-conductivity, low-sodium process waters typical of high-pressure steam cycles, deionized water loops, and wastewater treatment final effluents. Sample inlet requirements include flow rates of 10–40 L/h, temperature within 0–60 °C, and suspended solids <5 µm (no colloidal interference). The system complies with general industrial electromagnetic compatibility (IEC 61326-1) and safety standards (IEC 61010-1). While not pre-certified to FDA 21 CFR Part 11, its audit-ready calibration log storage, user-access-level controls, and timestamped event history support GLP/GMP-aligned operational qualification (OQ) protocols when deployed in regulated pharmaceutical or biotech water systems.
Software & Data Management
All calibration, alarm, and maintenance events are automatically timestamped and stored in a circular buffer with overwrite protection. Data export is supported via USB port (CSV format) for offline trending and regulatory review. Two-point calibration—using certified 200 mg/L Na⁺ standard and blank (e.g., ultrapure water)—automatically calculates empirical electrode slope and intercept, compensating for aging, coating, or temperature-induced drift. The instrument retains full calibration metadata (date, operator ID, standard lot numbers, measured mV values) to satisfy internal QA documentation requirements.
Applications
- Thermal power generation: Continuous monitoring of boiler feedwater sodium to prevent turbine blade corrosion and deposition.
- Chemical & fertilizer production: Control of sodium carryover in high-purity process condensates and scrubber solutions.
- Pharmaceutical water systems: USP and EP 2.2.42-compliant verification of purified water and water-for-injection (WFI) sodium limits.
- Municipal drinking water: Regulatory reporting of sodium content in desalinated or softened supplies per WHO and EPA guidelines.
- Electronics manufacturing: Monitoring rinse water resistivity and sodium contamination in wafer cleaning lines.
FAQ
What calibration standards are required for routine operation?
A two-point calibration using a 200 mg/L sodium standard solution and a low-sodium reference (e.g., ASTM D1193 Type I water) is recommended weekly or after electrode replacement.
Is the instrument suitable for high-salinity brine applications?
No—the TP-130 is optimized for trace sodium detection (sub-ppb to ppm range); it is not intended for seawater or concentrated brine where chloride interference and electrode saturation occur.
Can the device interface with a DCS or SCADA system?
Yes—via isolated 4–20 mA analog outputs and optional Modbus RTU (RS-485) communication module (sold separately), enabling seamless integration into plant-wide automation networks.
How often must the sodium electrode be replaced?
Typical service life is 12–18 months under continuous operation in clean, low-turbidity feedwater; lifespan decreases significantly in high-chloride, high-temperature, or abrasive sample matrices.
Does the system support automatic temperature compensation?
Yes—integrated PT1000 sensor provides continuous real-time compensation across 0–60 °C, applying the Nernst equation’s temperature coefficient to maintain pNa accuracy.
