Featured Analytical Sensors & Systems
Direct OEM factory configurations: 48-hour continuous burn-in aged, NIST-traceable calibrated, and certified for demanding electrochemical applications.
Why Procure TDS and pH Instrumentation from China?
Beyond competitive unit pricing: A systemic look at Shanghai BOQU's supply chain cluster, specialized glass-blowing craftsmanship, and dedicated high-temperature laboratories.
Specialized Formulation Glass
Unlike standard consumer probe makers, BOQU engineers proprietary low-impedance glass membranes formulated for heavy chemical exposure and cyclic steam sterilization reaching up to 130°C without mechanical failure or baseline drift.
Full Supply Chain Integration
From micro-signal analog frontend PCB development to CNC-machined titanium and 316L stainless steel sensor sleeves, local supply integration inside Pudong New Area guarantees unmatched cost-to-performance metrics and agility.
Rigorous Pre-Shipment Aging
Every industrial TDS transmitter and high-temperature pH probe undergoes a continuous 48-hour burn-in stress protocol alongside multi-point calibration standards before container sealing, mitigating on-site deployment failure rates.

System Solutions & Localized Use Cases
Engineered installations operating globally across seven industrial domains.
Sterile Biopharma & Fermentation
In bioreactors producing recombinant proteins or microbial enzymes, repeated sterilization in place (SIP) destroys standard reference electrolytes. BOQU’s pressurized gel electrolyte electrodes eliminate reverse contamination and drifting during prolonged fermentation runs.
Industrial RO Pretreatment & Desalination
Online total dissolved solids (TDS) and conductivity measurements safeguard reverse osmosis polyamide membranes from fouling and mineral scaling. BOQU DCA controllers provide automated continuous flush relay triggering whenever threshold set-points are violated.
Zero Liquid Discharge (ZLD) Effluent
Aggressive chemical effluent requires automated neutralization loops. Using high-impedance pHG-2081Pro controllers with integrated anti-interference shielding guarantees closed-loop chemical dosing accuracy without being skewed by adjacent variable-frequency drive noise.
