Features of TN-4110
- The TN measurement range is from 0-1 ppm to 0-200 ppm, with the dilution function up to 4000 ppm.
- Automatic dilution expands the analysis range and allows the reduction in salt, acid, and alkali concentrations to help reduce maintenance and extend catalyst life.
- A complete line of options designed to accommodate samples with suspended particles, reduce remedial maintenance in on-line TN measurement. 3 type of sample pretreatment units are available.
- Automatic calibration is incorporated using standard solutions stored on-board. Automatic calibration is possible even when using the on-board dilution function.
- On-board carrier/combustion gas purification allows use of air supplied from a compressor, thus eliminating expensive and potentially dangerous cylinder gases.
- Various input/output and alarm function allows a complete control via control station.
