Dissolved Oxygen Sensor withstands pressures up to 145 psi.
November 25, 2008 -
Featuring maximum error rate of less than 2%, Triton DO8 offers repeatability of ±0.5% and resolution of 0.01 ppm or 0.01% saturation. It provides 3 different outputs including 0-20 ppm, 0-200% saturation, or 0-500 psi, withstands ambient temperatures from 0-140°F, and records measurements at 20-120°F. Self-monitoring unit uses fluorescence quenching (FQ) optical technology coupled with microprocessor-based electronics, and stores calibration data within sensor.
New Triton DO8 Sensor with Optical FQ Technology Enhances Accuracy, Reduces Maintenance & Cuts Cost
Ideal For Drinking Water, Surface Water Monitoring, AquaCulture Municipal Wastewater Treatment, Industrial Water Treatment
Yorba Linda, CA-November 11, 2008-With a state-of-the-art fluorescence quenching (FQ) sensing element, the breakthrough Triton DO8 Dissolved Oxygen Sensor from Electro-Chemical Devices (ECD) delivers exceptionally accurate DO measurement with greatly reduced maintenance requirements for a low cost of ownership over a long service life in a wide range of municipal and industrial water treatment applications.
The trouble-free Triton DO8 Sensor is designed with precision FQ optical technology coupled with intelligent microprocessor-based electronics. The self-monitoring DO8 stores calibration data within the sensor, which minimizes maintenance over long service intervals while providing stable, dependable DO measurement.
The highly accurate Triton DO8 Sensor features a maximum error rate of less than 2 percent, repeatability of ±0.5 percent and resolution of 0.01 ppm or 0.01 percent saturation. It operates over a wide measurement range with three different outputs from 0 to 20 mg/l (0-20 ppm), 0-200 percent saturation or 0-500 hPa (0-6 psi).
Developed for rugged municipal and industrial water treatment environments, the tough Triton DO8 Sensor is designed to withstand ambient temperatures from -20 to 60°C (0-140°F) and records measurements at temperatures from -5 to 50°C (20-120°F). It withstands pressures up to a maximum of 10 bar (145 psi).
The Triton DO8 Sensor relies on a proven fluorescence quenching method to determine the oxygen concentration in water. A circular layer of optically-active, oxygen-sensitive molecules is integrated into an easily replaceable cap. This durable layer is highly permeable to oxygen and rapidly equilibrates to its surroundings. The cap aligns the optically-active fluorescence layer above two optical components inside the sensor-an emitter and a detector.
The sensor's emitter flashes a green light at the layer and the layer fluoresces back a red light. The duration and intensity of the fluorescence are directly dependent on the amount of oxygen in the layer. With little to no oxygen in the layer, the response is longer and more intense. The presence of more oxygen, however, quenches (reduces) the fluorescence effect.
The Triton DO8 Sensor continuously analyzes the oxygen level, water temperature and air pressure to calculate dissolved oxygen values. Via digital communications, the DO8 sends DO data to ECD's C-22 Controller, which provides a 4-20mA output signal to a water treatment plant's control room. The RS-485 digital signal is nearly immune to common EMI/RFI noise that is typically a problem in many plant environments.
Unlike amperometric sensors, the Triton DO8 has no membranes to replace, no electrolytes to refill and no anode/cathode assemblies to service or replace. The only service required is the simple replacement of the DO8's sensor cap, which lasts two years or longer, and the occasional wiping of the sensor head with a damp rag.
