Thermo 43i SO2

Pine Item #54385

Now available to rent, Thermo 43i SO2 the industry's new gas monitoring solution, the new iSeries platform delivers on all counts - and then goes a step further. Using pulsed fluorescence technology, the Model 43i measures the amount of sulfur dioxide in the air up to 100ppm. The pulsing of the U.C. source lamp serves to increase the optical intensity whereby a greater U.C. energy throughput and lower detectable SO2 concentration area realized.
