Once the quote is returned to CES-LANDTEC, the instrument is serviced. Below are some typical services:

Internal filters changed

All internal filters are replaced.

Oxygen (O₂) cell re-calibrated

The oxygen sensor will be re-calibrated, as the sensor output changes during its life-span this is usually carried out on all analyzers. This includes checking the 'RAW' value output of the sensor at various oxygen concentrations and with the use of proprietary software the instrument is programmed with the oxygen sensor characteristics.

Barometric sensor re-calibrated

The barometric sensor will be re-calibrated, as the sensor output may change during its life-span. This includes checking the 'RAW' value output of the sensor at known pressure levels and with the use of proprietary software the instrument is programmed with the sensor characteristics.

Methane (CH₄) and Carbon Dioxide (CO₂) sensors re-calibrated

The CH₄ and CO₂ sensors will be re-calibrated with the use of a temperature controlled environment and sophisticated computer analysis techniques. Click here to for more details on calibration.

All necessary modifications performed

The gas analyzer will automatically be upgraded with any necessary developments/modifications introduced in the period from the last service return.

Approved repairs

Any repairs quoted and accepted by the customer will be carried out.

Once servicing, repairs and calibrations are completed, the instrument goes through a Quality Control/Quality Assurance check.
