Transmitter
Sensor Oksigen Terlarut
Designed for continuous dissolved oxygen monitoring in water and wastewater processes, this optical dissolved oxygen sensor eliminates the limitations of traditional membrane-based probes. With no electrolyte, no oxygen consumption, and no flow dependency, it delivers stable, accurate measurements even in low-flow or static conditions.
It is especially suitable for applications where long-term stability, low maintenance, and reliable digital communication are critical.
Transmitters & Sensors Description
Why Optical Dissolved Oxygen Measurement
Traditional electrochemical DO sensors require membranes, electrolytes, and frequent maintenance. This optical dissolved oxygen sensor adopts fluorescence measurement technology, providing a fundamentally different approach:
No membrane, no electrolyte, no polarization
Tidak ada konsumsi oksigen selama pengukuran
Stable readings independent of flow velocity
Longer service life with significantly reduced maintenance cost
This makes it ideal for unattended operation and harsh field environments.
Dissolved O2 Sensor Features
Maintenance-Free Optical Technology
Membrane-free design with no electrolyte replacement
No polarization effect, no drift caused by oxygen consumption
Fluorescent cap is easy to replace when required
Accurate & Stable Measurement
Fast response time and excellent long-term stability
Minimal annual drift ensures consistent performance
Built-in temperature sensor with automatic temperature compensation
Designed for Field Reliability
Fully sealed IP68 housing for submersible installation
316L stainless steel + PPS body resists corrosion
Not affected by flow rate, bubbles, or low-velocity conditions
Digital Integration Ready
RS485 communication (Modbus-compatible)
Easy connection to PLC, SCADA, or upper-level control systems
Dissolved Oxygen Sensors Applications
Wastewater treatment (aeration basins, biological tanks)
Pemantauan air permukaan dan lingkungan
Aquaculture and fish farming systems
Industrial process water
Municipal water and utility monitoring
Dissolved Oxygen Sensor Designed for Long-Term Operation
By removing consumable components and minimizing maintenance requirements, this dissolved oxygen sensor significantly reduces total cost of ownership while ensuring reliable data for process control and environmental compliance.
It is not just a sensor—it is a long-term monitoring solution.

Ya.
This sensor uses optical fluorescence technology and does not consume oxygen during measurement. The reading is independent of flow velocity, making it highly reliable in low-flow or stagnant conditions.
The optical measurement principle is far less sensitive to bubbles than electrochemical sensors. Occasional bubbles do not significantly affect readings, especially in aeration tanks or mixed water environments.
The sensor features minimal annual drift and no electrolyte consumption. Compared to membrane-based DO probes, it maintains accuracy over long periods with significantly reduced recalibration frequency.
Routine maintenance is minimal.
There is no membrane or electrolyte to replace. The fluorescent cap has a long service life and can be easily replaced when required, reducing downtime and maintenance cost.
Ya.
The sensor supports RS485 communication, typically using Modbus protocol, allowing seamless integration with PLC, DCS, SCADA, and data logging systems.
Absolutely.
With an IP68-rated housing and 316L stainless steel + PPS construction, the sensor is designed for continuous submersible operation in corrosive, high-humidity, and industrial wastewater conditions.
