EC92DIS Portable Oxygen Analyser Trace and Percentage (ATEX approved) Suitable for Hazardous Environments Applications Offshore Gas purity checking Hydrogen plants Chemical plants Pharmaceutical plants Oil refineries Petrochemical Centrifuges Inert atmospheres and cylinder gas analysis in hazardous area Features & Benefits Unique fast purge system Intrinsically safe certification Easy calibration Selectable ranges % and ppm Maintenance-free measuring cell Powered by 2 x PP3 batteries This instrument has a 36 month warranty which covers any faulty workmanship and normal component failure relating to electronic circuit cards The EC92DIS portable oxygen analyser will detect levels of oxygen as low as 1ppm, up to high percent levels and can be used on most industrial gases and atmospheres. There is no need for routine maintenance of the fuel cell, and the instrument may be easily calibrated, using ambient air or standard calibration samples. Unique fast purge system The innovative design of the fast purge/cell Operation of the EC92DIS is made easy by seal system means readings of single digit the internal sample system. Taking gas parts per million oxygen can be obtained measurements is simply a matter of within a few minutes. Apart from a single connecting the gas line, purging for a short switch, no adjustments or controls are time and switching a valve position. When necessary, making the unit ideal for use by not in use the cell is sealed. non-technical personnel. Approved by BASEEFA and CENELEC to ATEX II 1G Ex ia IIC Ga T4 standards Easy calibration The digital display is easily visible in sunlight or low level light; can display readings below 1 part per million and indicate low battery power. A calibration adjustment on the front panel can be set to give a reading of 20.9% when the analyser is working on clean air. Using this method ensures that the instrument will be absolutely accurate on any selected part of its operational range. If calibration of trace levels is required, certified calibration gas may be used. Maintenance-free measuring cell Intrinsically safe certification Each sensor is individually tested to meet The instrument provides best in class stringent performance specifications. The certification compared to any other trace micro-fuel cell is sealed and is simply oxygen analyser in the market place. replaced when exhausted. The normal Unlike any other analyser it can be used in lifetime for % measuring instruments is 3 Zone 0 / Division 1. The instrument may years while trace sensors can last for several also be used in safe/non hazardous areas years, unlike others which may only function and the batteries may be replaced by for several months. rechargeable types.
