QED Environmental Systems Gas Analyzer Biogas 5000

Warning: The battery charger is NOT covered by the Ex certification. The battery must be charged only in a safe area.

Note: To charge, the analyzer must be switched OFF before attaching the charger. Switching the analyzer on or off during charging will cancel the current charge. The analyzer should be left OFF during the charging cycle.

The battery charger is intelligent and will indicate when the unit is charging and charged. The charger should only be disconnected when fully charged is indicated.

The instrument must be charged ONLY using the battery charger supplied with the instrument. The battery charger supplied is intended for indoor use only. Please ensure adequate ventilation while charging.

Note: Connect the charger to the mains attaching the appropriate adaptor. Contact LANDTEC for further information.

Note: This charger has been internally restricted to 1.5A

A full charge will take approximately 3-4 hours. Typically, a fully charged battery will last 7- 8 hours. A quick 30 minute charge can be used to give approximately one hour of use in the field but may shorten the battery life. The battery charge status will be indicated on the charger plug.

Temperature can dramatically affect the battery life; please take this into account when estimating battery life. The unit should be switched-off while charging to give a complete and consistent charge. Turning off Bluetooth and dimming the contrast will increase battery life.

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

Manufacturer’s service due date

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.

Warning Calibration gases can be dangerous. For each gas used the appropriate material safety data sheet must be read and understood before proceeding.

CH4, CO2 and O2 can be measured by BIOGAS 5000 gas analyzer as standard

The BIOGAS 5000 instrument can have a H2 compensated CO channel

For the other gas channel options contact LANDTEC for advice.

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.

The BIOGAS 5000 gas analyzers can be checked against a known concentration of gas, to give confidence that the analyzer is operating as expected at the time and conditions in which it is being used.

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.

- Gas port connectors: Periodically check that the O-rings on the gas port connectors are not damaged. A damaged O-ring can let air into the sample gas and result in incorrect readings. If the O-ring is damaged, the complete gas port connector should be replaced.;

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.

All necessary ID codes and information have been uploaded from GAM to the analyzer

The instrument has the correct time and date set

The water trap filter is fitted and is clean and dry

The channels have been zeroed, without gas concentration present

Check the span calibration with a known concentration calibration gas
