BWS-MP multi-parameter water quality analyzer
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: Enhances reference electrolyte stability and extends service life.
●Ceramic Junction Interface: Slows KCl leaching for longer operational lifespan.
●Oil-Based Internal Reference: Minimizes clogging at the junction.
●Thick High-Impedance Bulb: Robust structure resists particle impact and breakage.
●PPS Housing: Corrosion-resistant and withstands high temperatures.
●Front Thread with Protective Fittings: Impact-resistant for immersion and maintenance.
●Rear 3/4NPT Waterproof Thread: Seals securely without PTFE tape.
●IP68 Rating: Prevents damage from environmental and human factors.
