Is BOQU a manufacturer or a trading company?

BOQU is a manufacturer. Founded in 2007, Shanghai Boqu Instrument Co., Ltd. designs, produces and tests its sensors and analyzers in two Shanghai facilities (Kangqiao and Lingang) with 4,632 m² of floorspace, 200+ employees and an annual output of more than 100,000 instruments.

Which certifications do BOQU water quality instruments hold?

Production is managed under ISO 9001 and ISO 14001 systems, and products carry CE, SGS and FDA related certifications. The pH5806 high temperature pH sensor has also been awarded the Shanghai Brand certification.

What signal outputs and communication protocols are available?

Depending on the model, BOQU online analyzers provide 4-20 mA analog outputs, relay alarm contacts and RS485 Modbus RTU communication. IoT digital sensors output RS485 Modbus RTU directly, so they can connect to PLC, DCS, SCADA or cloud gateways without a separate transmitter.

Can BOQU sensors be used in high-temperature fermentation and steam sterilization?

Yes. BOQU operates a dedicated high-temperature water quality sensor laboratory, and its high-temperature pH and DO sensors such as the pH5806 and DOG-208FA are designed for bioreactors, fermenters and hot process lines that undergo repeated steam sterilization.

Do you offer OEM and ODM services?

Yes. BOQU supports OEM and ODM projects including private labeling, custom housings, cable lengths, measuring ranges, firmware and communication protocols, backed by an in-house R&D team.

What information should I provide to get the right analyzer recommendation?

Please share the parameters to measure, expected range, water type, process temperature and pressure, installation method (immersion, flow-through or pipeline), required output signal, power supply and any local compliance standard. BOQU engineers will then recommend a suitable configuration.

Metrology & Market Economics

Turbidity Meter Price Architecture & Global Industrial Dynamics

Understanding cost tiering, optical design, compliance drivers, and total cost of ownership across process automation sectors.

Optical Architecture & Sensor Physics

Turbidity meter pricing varies directly with optical path engineering. ISO 7027 compliant near-infrared (860 nm LED) scattering reduces color interference in complex matrices, whereas USEPA 180.1 tungsten lamp systems require stable power regulation. High-tier immersion sensors feature sapphire optical windows, silicon photodiodes, and integrated dual-beam ratio metric compensations to mitigate source aging and temperature drift.

Self-Cleaning & Field Maintenance

The operational total cost of ownership (TCO) is heavily influenced by mechanical maintenance. Premium factory configurations embed automated mechanical wiper systems or ultrasonic transducers to eliminate biofouling and particulate encrustation in wastewater treatment plants (WWTP) and activated sludge loops (MLSS), reducing routine site interventions from bi-weekly to quarterly.

Industrial Digital Protocols & IoT

Direct digital RS485 Modbus RTU communication eliminates costly external transmitters and analog signal degradation over extended cable runs. Smart sensors house internal microprocessors storing calibration curves, run-time diagnostics, and temperature algorithms, enabling direct connectivity to distributed control systems (DCS), PLC panels, and SCADA IoT cloud telemetry.

Frequently Asked Questions on Turbidity Meters & Manufacturing

Comprehensive guidance directly from BOQU’s field instrumentation and export engineering teams.

What factors most strongly influence the factory price of a turbidity meter in China?

Pricing is governed primarily by optical accuracy tiers (low-range potable water vs. high-range MLSS sludge), optical source configuration (infrared 860nm vs. white tungsten light), body materials (POM plastic vs. 316L stainless steel or Titanium for corrosive media), integration of motorized mechanical cleaning wipers, and internal processing capabilities (raw analog sensor vs. digital smart probe with RS485 Modbus RTU onboard).

Is Shanghai BOQU Instrument a direct manufacturer or a trading company?

BOQU is a direct manufacturer founded in 2007 in Shanghai, China. We operate two integrated facilities in Kangqiao and Lingang with over 4,632 square meters of production space, in-house optical calibration benches, automated PCB wave soldering lines, and complete testing laboratories producing over 100,000 analytical instruments annually.

What is the difference between ISO 7027 and USEPA 180.1 compliant meters?

ISO 7027 utilizes a near-infrared LED operating at 860 nm with a narrow bandwidth. This minimizes sample color interference (essential in wastewater and effluent). USEPA 180.1 mandates a tungsten-filament lamp operating between 400–680 nm, providing higher sensitivity to fine particles in low-turbidity drinking water applications under 1.0 NTU.

Can BOQU turbidity sensors and analyzers be customized via OEM/ODM?

Yes. We provide complete OEM/ODM options for international distributors and equipment builders, including private label branding, customized immersion cable lengths, modified Modbus register address maps, tailored enclosure form factors, and bespoke calibration ranges for special industrial solutions.

What maintenance and calibration intervals are recommended for online turbidity systems?

Sensors fitted with automated mechanical wipers in typical municipal effluent require manual physical inspection only every 3 to 6 months. For drinking water flow-cell setups, zero-point verification with bubble-free zero water is suggested quarterly, with full Formazin standard calibration recommended annually.
