Product Overview
- Product overview
Product Features
The DOG-209FYA is an optical dissolved oxygen sensor from BOQU designed for continuous DO measurement. It has a CPVC/PVC or stainless steel 316 body, replaceable membrane-cap module, M9 male connector, IP68 rating and provides a 4–20 mA output. Measurement range is 0–20 mg/L (0–200 % sat), operating temperature -5 to 50 °C.

Product Advantages
Key features include optical (luminescent) sensing technology, a grit-mesh metal membrane for improved stress resistance and durability, replaceable membrane cap module, IP68 water protection, fast response (T90 ≈ 30 s; 60 s to 100%), and an expected luminophore module life of about 2 years. High-precision readings (DO ±0.1 mg/L, Temp ±0.2 °C, Sat% ±1%) and M9 connector simplify installation and integration.
Application Scenarios
- Product value
The sensor delivers stable, drift-resistant DO measurements with minimal routine maintenance, enabling reliable long-term monitoring and better process control. Fast response and high accuracy help operators optimize aeration, reduce energy and chemical costs, and maintain regulatory compliance. 4–20 mA output enables easy integration into controllers and PLC/SCADA systems.
- Product advantages
Advantages include optical technology (no consumable electrodes or frequent calibration), rugged grit-mesh metal membrane for harsh environments, replaceable cap to reduce downtime and service cost, IP68 protection for submerged use, durable materials (CPVC/PVC or SS316), and precise, repeatable readings. BOQU’s quality control and after-sales support (service guarantees and quick reply) further increase reliability and user confidence.
- Application scenarios
Suitable for continuous DO monitoring in urban sewage treatment, industrial wastewater treatment, aquaculture and hatcheries, environmental monitoring of rivers/lakes, and other harsh or demanding process-control environments where stable, low-maintenance dissolved-oxygen measurement is required.
