Description
The QED GEM PRO is a portable biogas designed to offer maximum flexibility and productivity in the field. It can measure up to 7 gases simultaneously: CH₄, CO₂, CO, O₂, H₂S, H₂, NH₃. Designed in a modular fashion, the GEM PRO allows gas modules to be replaced or added directly on site, thanks to its pre-calibrated modules, eliminating the need to send the instrument back to the workshop. As a result, maintenance is quick, downtime is reduced, and your analyzer remains available at all times.
The QED GEM PRO is equipped with a high-definition touchscreen and professional GAMSoft software for simplified data collection and export. This allows you to quickly monitor and optimize your biogas installations, while benefiting from a clear and detailed visualization of measurements.
Lightweight and robust, it adapts perfectly to demanding field conditions, while offering maximum measurement accuracy and reliability. Equipped with a removable battery, it offers full autonomy for the entire day, allowing you to work continuously without interruption.
In addition, the QED GEM PRO is ATEX Zone 1 certified, in accordance with international safety standards for biogas analyzers.
Available for rent
CleanAir Europe offers the QED GEM PRO for rent starting from one day, for your biogas measurement and detection needs.
