Series FEM 55
Series FEM 55 are microprocessor based portable fuel efficiency monitors whose architecture ensures simplicity in use, trouble-free performance, cost effectiveness and reliability. Stored data can be viewed or downloaded to a computer or printed out by an external printer. FEM-55 measures Oxygen and Carbon dioxide [O₂ CO] and ⁰C and calculate values of % Carbon dioxide [CO₂,] % excess air, net and gross efficiencies for fuels. Date, time, name of owner & company are user programmable. Optionally FEM 55 can be configured to measure five gases example : O2, CO, SO2, NO & NO2.
