Maintenance
Although the XTDL-HT™ laser cell is designed to withstand
high level of contamination, the instrument is
recommended for periodic cleaning to prevent
contamination buildup on the gas sampling line. Annual
inspection and cleaning are sufficient for general use, more
often for dirty application. Maintenance procedure
includes:
1. Check the pressure regulators and pressure gauge for
correct pressure. Remove and clean if necessary.
2. Check the flow meter for correct flow rate. Remove and
clean if necessary.
3. Flush the sampling system with solvent appropriate for
the application.
4. Remove bottom of the laser cell and drain any liquid.
Clean before re-installing.
