The fundamental distinction lies in the optical light source and detector wavelength. The ISO 7027 standard dictates a monochromatic Near-Infrared (NIR) light-emitting diode (LED) at 860 nm with a 90° scattered light detector. Because water and typical dissolved organic chemicals do not absorb light at 860 nm, ISO 7027 sensors are largely unaffected by sample coloration. In contrast, US EPA 180.1 specifies a tungsten-filament lamp emitting broad-spectrum white light between 400 and 680 nm. EPA 180.1 offers superior sensitivity for ultra-low turbidity particle detection below 0.05 NTU, but is vulnerable to color-induced absorption errors. BOQU manufactures both configurations to ensure global regulatory compliance.

Entrained microbubbles act as reflective surfaces that scatter light identically to suspended solid particles, generating false spikes. For direct pipe mounting, BOQU utilizes angled optical flow geometries that sweep bubbles across the optical face. For low-range drinking water applications (such as our MPG-6099Plus system), we integrate an upstream stainless steel or acrylic baffle de-bubbler chamber. The bubble trap forces the fluid through a tranquilizing labyrinth, allowing buoyant air pockets to disengage to the atmosphere before the sample enters the optical measuring cell.

For biological wastewater, sewage sludge, and industrial effluents where grease and biofilm accumulate rapidly, BOQU equips the ZDYG-2088-01QX and related models with an integrated motorized mechanical scraper wiper. The programmable wiper features a chemically inert fluoroelastomer blade that cleans the sapphire optical window at user-defined intervals (e.g., every 15, 30, or 60 minutes). Furthermore, our titanium-bodied submersible probes can be integrated with compressed air blast or pressurized water jet cleaning nozzles directed at the optical interface.

Yes. BOQU's IOT series sensors (including our digital turbidity, DO, and pH units) feature internal signal processing microcontrollers. They output direct RS485 Modbus RTU communications at standard 9600 / 19200 baud rates alongside raw 4-20mA signals. You can wire the sensor cable directly into your Siemens, Allen-Bradley, Schneider, or Mitsubishi PLC analog/digital input cards, saving significant budget by avoiding redundant wall-mounted transmitters.

Because BOQU produces sensors, PCBs, and flow cells in-house across our Kangqiao and Lingang factories, standard sensor models have a low MOQ of just 1 unit for evaluation, with typical dispatch in 3 to 7 business days. For customized OEM private-label branding (laser logo engraving, custom cable lengths, tailored firmware, or custom housing alloys), typical lead times range from 2 to 3 weeks depending on batch volume.
