Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative environmental products and a subsidiary of Graco Inc., announces the new SEM Rover. The SEM Rover provides functional improvements to the LANDTEC SEM5000 methane (CH4) detector, and is ideal for landfill surface emissions monitoring (SEM). The new tool is the result of collaboration with landfill operators to improve efficiency.

The SEM Rover is a wheeled sampling wand which enables compliance with sampling regulations, regardless of terrain or field conditions. The SEM Rover is constructed of a lightweight, high-strength aluminum framework with a durable, high-visibility powdercoat finish. Operator ease is emphasized with an adjustable push handle. Three large wheels maintain stability and ease transit over all types of ground as the SEM Rover holds the sample wand inlet at a consistent five centimetres from the ground. The SEM Rover will help minimize operator fatigue and speed up sampling on fields where grounds are not regularly maintained.

Utilizing patented LASER technology, the SEM5000 methane detector brings unmatched reliability, accuracy and ease of use in one package. Unlike flame ionization devices (FID), the SEM5000 methane detector has a very short start-up time (less than two minutes) and no risk of flame-out and associated restart. There is no need to carry an external gas bottle during sampling, and most importantly, there is no open flame in a potentially explosive environment.

The SEM 5000 methane detector offers on-board GPS tracking, built-in memory for up to 450 hours of sampling and automatic report generation. The SEM Rover maintains proper sample probe height, orientation and shielding from transient wind as described in EPA Method 21 – Determination of Volatile Organic Compound Leaks. The collected sample data can be easily downloaded via Bluetooth connectivity to a PC to automatically generate standard compliance reports.

The SEM5000 methane detector and new SEM Rover make up a lightweight, ergonomic surface emissions monitoring package which weighs about half as much as competitive alternatives. For more information, visit QED online at www.qedenv.com.
