Our IoT-compatible 2-in-1 water sensor integrates pH, conductivity (EC), and temperature measurement into a single rugged probe. Featuring industrial-grade electrodes and advanced digital signal processing, it delivers laboratory-grade accuracy (pH±0.03, EC±1.5%FS, Temp±0.2°C) with real-time LCD display.
Features:
(A)Internal use of axial capacitance filtering, 100MΩ resistor to increase impedance and enhance stability.
pH Measurement:
Utilizes a glass electrode to detect hydrogen ion activity, converting potential difference to digital values with automatic temperature compensation (ATC) for accuracy across environments.
EC Measurement:
Applies AC voltage between electrodes to measure solution resistance, calculating conductivity while minimizing polarization effects through smart algorithms.
Critical Parameters:
pH: 6.5-8.5 (regulatory compliance)
EC: Indicates TDS levels
Configuration Tip: Opt for anti-fouling probes with optional auto-cleaning attachments
Use Cases: Aeration tank monitoring, effluent quality control
Optimal Ranges:
