Available add-on options for the LEMS include:
• Filter system for OCEC particle analysis
• Tedlar bag system for analysis of greenhouse gases (such as methane)
• Gravimetric (filter-based) PM quantification
• Contact us for additional option possibilities
The LEMS analysis software is compatible with Windows and can process data from either a Water Boiling Test (WBT) or a Controlled Cooking Test (CCT) using the automated data processing spreadsheets. Personnel with reasonable computer experience can run the LEMS, which comes with a comprehensive instruction manual.
The LEMS can be used for various testing procedures:
WBT – the standard laboratory test for optimizing cooking stove designs.
CCT – Testing what happens when a local cook prepares common meals using both the traditional and improved stoves for comparisons.
QUALITY CONTROL – When many stoves are produced, a random sample can be selected and tested to ensure performance is up to specifications.
CARBON CREDITS – With CO2 measurement built-in, and a methane add-on available, actual emission factors can be measured and used in place of the IPCC defaults when carbon credits are being used. Gold standard has accepted measurements from the LEMS as an excellent alternative to IPCC defaults – which can help to provide higher carbon credits due to more accurate measures of improved stoves.
