## Description

This industrial-grade pH combination electrode features a sensitive glass membrane with low impedance, delivering fast response times, good thermal stability, and excellent reproducibility across the full 0–14 pH range. The Ag/AgCl gel electrolyte reference system provides a stable half-cell potential, while the ring PTFE membrane resists clogging for long-term online monitoring. The electrode connects via a standard BNC connector and includes a 5 m cable for flexible installation. It outputs 0–5V linearly corresponding to pH 0–14 and is compatible with DFRobot Analog pH Meter boards (SEN0161, SEN0169) as a probe upgrade. Specifications Measuring Range – 0–14 pH Measuring Precision – ≤0.02 pH Response Time – 10 seconds Drift – ≤0.02 pH / 24 hours Slope – ≥95% Equipotential Point – 7 ±0.5 pH Membrane Resistance – ≤200 MΩ Temperature Range – 0–60°C Connector – BNC Cable Length – 5 m Electrode Length – 177 mm (with protective cover) Diameter – 27.4 mm Key Features Armoured Casing – Durable construction for industrial environments Ring PTFE Membrane – Resists clogging for long-term use Ag/AgCl Reference System – Stable, anti-pollution performance Linear Output – 0–5V across 0–14 pH range Low Impedance Glass Membrane – Minimal alkali error Ideal For Industrial wastewater and sewage pH monitoring Printing and circuit board factory effluent testing Long-term online pH detection Upgrading DFRobot pH meter kits (SEN0161, SEN0169) Package Contents 1× H-101 pH Electrode 1× pH Electrode Manual Resources Product Wiki
