In the Lab

When your LANDTEC instrument reaches our service facility, its condition is assessed with the following tests and checks:

General operations
The main functions of the gas analyzers operation are checked to ensure that they are within specification.
Barometric pressure reading
The barometric pressure reading is checked to ensure it is within specification. This is carried out by way of comparing the atmospheric reading against a known standard. If necessary, reprogramming is quoted.
Static and differential pressure readings
The static and differential pressure transducers are checked to ensure they are within specifications. This is carried out by comparing instrument readings to a known standard, applying a known pressure and noting both readings. If necessary, reprogramming will be quoted.
Pump functionality (flow and vacuum)
All flow and vacuum functions of the internal pump are checked to ensure the operation is within specification.
Water ingress/blockage
The internal filters are checked for cleanliness and moisture ingress to ensure they are not contaminated.
Flow fail setting
The flow fail function is checked to ensure proper operation within the specified limits.
Gas pod and Temperature probe connectivity reading
The connectivity of the gas analyzer is checked to ensure correct operation and reading performance with accessories.
Computer controlled gas check
Inward and outward gas checks are carried out by way of connecting the gas analyzer to a custom built computer controlled 'gas checking rig' and proprietary software. At the inward stage, two sets of readings are taken - one using the customer's calibration settings and a second set using factory calibration settings. During this process a range of gases are used that span the reading range of the gas analyzer.
Structural and aesthetics check
The instrument is checked for cracks, scratches and broken or missing pieces.

After the assessment is made, a quote is issued for all items needing repair/replacement, including all warranty items and standard servicing and calibration. The quote is then sent to the customer for item-by-item approval.
