QED Environmental Systems Gas Analyzer GEM 5000

Warning: Inhaling hydrogen sulphide gas (H2S) or other harmful gases can cause death. It is the responsibility of the user to ensure that he/she is adequately trained in the safety aspects of using H2S and other harmful gases. In particular, where hazardous gases are being used the gas exhausted from the analyzer must be piped to an area where it is safe to discharge the gas. Hazardous gas can also be expelled from the instrument when purging with clean air.

Warning: This maintenance check requires trained personnel with PPE!

Note: This does not replace the factory service and calibration. If this calibration is completed incorrectly it may decrease the accuracy of the gas analyzer.

The BIOGAS 5000 instrument can have a H2 compensated CO channel. This option requires that H2 be used in the calibration process.

Zero: The point at which the gas analyzer is calibrated when there is none of the target gases present.

Span: The point at which the gas analyzer is calibrated when a known quantity of the target gas is present.

It is recommended that the instrument be regularly serviced and calibrated by LANDTEC in accordance with the due date on the instrument.

Zeroing of the gas analyzer should be undertaken at the start of each day’s monitoring.

Use historical data to drive your frequency of calibration.

The results of the calibrations will need to be recorded to monitor over time whether the frequency of calibration needs to be increased or decreased relative to the confidence required.

The GEM5000 gas analyzer should be regularly serviced to ensure correct and accurate operation.

LANDTEC recommends a service and recalibration every 12 months.

The BIOGAS 5000 range is ATEX certified for use in potentially explosive areas. As such it should be serviced only by qualified engineers.; Failure to observe this will result in the warranty becoming invalid and could invalidate the ATEX certification.

Warning: If the BIOGAS 5000 is to be serviced by trained LANDTEC personnel. Service by any untrained personnel will negate service. If serviced by unqualified engineers, the ATEX certification may be invalidated and the instrument may be unsafe for use in a potentially explosive atmosphere.

There are no user serviceable parts inside the instrument.

The following parts can be user serviced:

- In-line water filter: This should be regularly inspected for obstructions, moisture or damage and changed if needed. The instrument should never be operated without the in-line water filter as this may result in water entering the instrument.

-Sample tubing: Always ensure that sample tubes are not contaminated or damaged.

Warning: The self-test should only be done with the analyzer sampling fresh air.
