UV-Photo-X Fluorescence Analyser – MODEL 6650B
The ability to monitor the concentration of an analyte in a process stream is critical for accurate and reliable process control. There are many techniques used to determine the analyte concentration of interest. One of the most sensitive sensing techniques is molecular fluorescence. Fluorescence occurs when a molecule absorbs light energy, either ultraviolet or visible, and rapidly emits light, at some longer wavelength. Fluorescence of this type is referred to as Stokes fluorescence. Fluorimetry characterises the excitation and emission properties of the molecular species.
LXT-220
Model LXT-220 Dissolved Oxygen Controller is a robust and versatile instrument for the measurement and process control of dissolved oxygen in a liquid component. Customisable, the Model LXT-220 comes standard with a single 4-20mA current output but can have as many as five. The current output is field selectable and may be expanded to any range within the transmitter’s full operating range. It can also be programmed as reverse acting; for example, a 4-20 mA output for a range of 0 to 10 ppm can be reversed to 10 to 0 ppm.
- Front panel membrane switches
- Menu driven backlit display with contrast adjustment
- Automatic calibration: this allows calibration points to be defined upon initialisation of the transmitter
- An easy back to factory calibration menu allows the instrument to return to a predetermined factory calibration. The default parameters are: zero electrode offset and –157.5mV/FS slope.
- 4-20mA current output fully expandable to any range within the transmitter’s full operating range. The output is field selectable and fully programmable. The current output can be configured to be reverse acting
- Temperature conversion: temperature can be displayed in either Fahrenheit or Celsius. The units can be toggled from one to the other in the field with the conversion calculation performed automatically

The Model LXT-280 transmitters provide solutions to a variety of liquid analytic applications involving hazardous areas.
- Magnetic switches located behind a glass window can be activated without having to open the instrument
- Menu driven backlit display with contrast adjustment
- Automatic calibration: this allows calibration points to be defined upon initialisation of the transmitter
- An easy back to factory calibration menu allows the instrument to return to a predetermined factory calibration. The default parameters are: zero electrode offset at 0 ppm or 0% oxygen and -400 mV at full scale
- 4-20mA current output transmitted on the same 24 VDC power wiring. The current output is fully expandable to any range within the transmitter’s full operating range. The current output can be configured to be reverse acting
- Temperature conversion: temperature can be displayed in either Fahrenheit or Celsius. The units can be toggled from one to the other in the field with the conversion calculation performed automatically
Sentinel Analysers
Teledyne offers two proven standard sensor configurations as functioning receptacles for its Oxidation Reduction Potential (ORP) cartridge. The SP-1 immersion or the SP-2 valve retractable sensors come in a variety of materials to further enhance the resistance of aggressive corrosion aqueous media and can be ordered in varying lengths to meet installation requirements.
- Teledyne’s ORP electrode and sensor have a low physical profile (3/4” dia) that allows for greater ease of insertion into potentially high flow rate/pressure pipelines
- Selectable sensor housing lengths allow for reaching deep aeration basins or vats
- The ORP electrode (cartridge) is replaceable (as a component of the sensor) at a much lower life cycle cost than that of the competition
- The sensor has a preamp (signal conditioner) integral to the sensor that provides a cleaner signal for transmission over longer cable lengths
- Attempting to measure ORP with a pH electrode will yield an unacceptable offset in mV. An oxidising agent such as quinhydrone (cyclohexadiene) must be added to the buffer to develop a measurement standard
- Being acidic, the quinhydrone must be used at 7pH or less (4pH). This will approximate a correct mV reading of 59.1 per decade
Alkalinity Analyser – Model 6800
Model 6800 Alkalinity Analyser utilises a direct measurement of Alkalinity measurement. Unlike titration method, the 6800 measures the CO2 concentrations derived from analysis of Total Inorganic Carbon (TIC), using interference-free infrared technology. Both methods are compatible, since each uses the same stoichiometric relationships. For convenience in relating the technologies, phenolphthalein alkalinity id determined.
- Alkalinity/Direct Detection Method
- Avoids Titrimetric/Colorimetric Procedures
- Reports total alkalinity
- Requires no probes
- Integrates with Teledyne TOC Platform
- Interference free analysis
- Completely automatic
- Rapid response
