Precision pH Electrode for Accurate Water & Soil Analysis
High-sensitivity RS4 pH electrode ensures fast, stable readings with a measurement range of 0–14 pH and ±0.01 pH accuracy. Features durable epoxy body and double-junction reference system for enhanced contamination resistance, ideal for harsh wastewater environments.
Industrial-Grade Durability
Built with a robust sensing glass bulb and sealed reference electrolyte to prevent leakage, extending lifespan even in high-temperature or high-salinity conditions. Compatible with most pH meters via standard BNC connector.
Versatile Applications
Perfect for wastewater treatment plants, hydroponics, aquaculture, soil testing labs, and industrial process monitoring. Low-maintenance design reduces calibration frequency, saving time and costs for bulk users.
Wholesale Advantage
Direct factory pricing with no middlemen—optimized for large-quantity orders. Global shipping ensures reliable supply for distributors and institutional buyers. Strict QC guarantees consistent performance across all units.
