{"title":"Industrial pH Electrode - Armor Casing","handle":"industrial-ph-electrode-armor-casing","url":"/products/industrial-ph-electrode-armor-casing","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.\n\nThe 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.\n\nSpecifications\n\n\nMeasuring Range – 0–14 pH\n\nMeasuring Precision – ≤0.02 pH\n\nResponse Time – 10 seconds\n\nDrift – ≤0.02 pH / 24 hours\n\nSlope – ≥95%\n\nEquipotential Point – 7 ±0.5 pH\n\nMembrane Resistance – ≤200 MΩ\n\nTemperature Range – 0–60°C\n\nConnector – BNC\n\nCable Length – 5 m\n\nElectrode Length – 177 mm (with protective cover)\n\nDiameter – 27.4 mm\n\n\nKey Features\n\n\nArmoured Casing – Durable construction for industrial environments\n\nRing PTFE Membrane – Resists clogging for long-term use\n\nAg/AgCl Reference System – Stable, anti-pollution performance\n\nLinear Output – 0–5V across 0–14 pH range\n\nLow Impedance Glass Membrane – Minimal alkali error\n\n\nIdeal For\n\nIndustrial wastewater and sewage pH monitoring\nPrinting and circuit board factory effluent testing\nLong-term online pH detection\nUpgrading DFRobot pH meter kits (SEN0161, SEN0169)\n\n\nPackage Contents\n\n1× H-101 pH Electrode\n1× pH Electrode Manual\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11352,"title":"Default Title","sku":"DF-FIT0348","price":91.96,"on_sale":false,"in_stock":true,"available_quantity":14,"option1":"Default Title"}]}
