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
