The online pH sensor adopts the glass electrode method with a corrosion-resistant housing. It features a built-in NTC temperature sensor for automatic temperature compensation and communicates via RS485 using the standard Modbus protocol.
●Dual Salt Bridge Design: Strengthens resistance to reference electrolyte contamination and extends service life
●Ceramic Reference Junction: Slows KCl diffusion to prolong operational lifespan
●Oil-Based Internal Reference: Reduces the risk of clogging at the junction interface
●Thick, High-Impedance Bulb: Reinforced structure resists breakage from particle impact
●PPS Housing: Excellent corrosion and high-temperature resistance
●Front Thread with Protective Sleeve: Impact-resistant during immersion installation and maintenance
●Rear 3/4" NPT Waterproof Thread: Enables secure sealing without PTFE tape for immersion use
●IP68 Protection Rating: Minimizes damage from harsh environments and handling errors
