Wholesale Salt Conductivity Meter Manufacturer & Pricelist

Contacting conductivity sensors use direct electrode-to-liquid contact (2-electrode or 4-electrode systems), which excel in high-purity water and moderate salinity ranges (0.01 µS/cm to 20 mS/cm). However, when measuring heavy salt concentrations, brines, or slurries (>50 mS/cm), contacting electrodes suffer from polarization resistance and scale encrustation. Inductive (toroidal/electrodeless) sensors utilize two hermetically sealed magnetic coils inside a PFA or PVDF casing. The induced current in the electrolyte is detected without bare metal contact, virtually eliminating sensor fouling, chemical corrosion, and routine maintenance in harsh industrial applications.

Conductivity exhibits strong temperature dependency, typically shifting 1.8% to 2.2% per degree Celsius in saline water. All BOQU salt conductivity meters incorporate built-in precision Pt100, Pt1000, or NTC2.2k thermistors housed adjacent to the sensing core. Transmitters feature programmable temperature compensation curves (linear, pure water non-linear, and high-concentration salt compensation matrices) referenced to standard 20°C or 25°C benchmarks to ensure accurate, repeatable process tracking across changing thermal conditions.

Yes. Shanghai BOQU Instrument supports full OEM/ODM partnerships for global distributors and equipment manufacturers. Our engineering scope includes laser-etched private branding, custom housing colors, tailored firmware splash screens, specialized Modbus register mappings, unique cable assemblies, and customized process fittings (Tri-Clamp, NPT, flanged, or submersion brackets).

Every production batch includes an individual Factory Calibration Certificate referenced to traceable NIST standards. For enterprise contracts, we provide Certificates of Conformity (CE), ISO 9001 quality audits, material compliance sheets (FDA, USP Class VI on sanitary models), and ingress protection test reports (IP65/IP68).

Standard catalog items feature an MOQ of 1 to 5 units, with stock orders dispatching within 3 to 5 business days. Custom OEM configurations typically maintain an MOQ of 10 to 20 units with lead times between 10 and 20 business days depending on specific cable lengths, housing molds, and testing requirements. Expedited global express air shipping delivers directly to your facility in 3 to 7 working days.
