The Eagle 2 from RKI Instruments can simultaneously detect and display up to six different gases. The company's sensor technologies include a photo ionization detector (PID sensor) for monitoring low ppm VOC gases. The monitor also has the ability to detect combustible gases in PPM, % LEL, or % volume ranges with the capacity to auto range based on the incoming sample. Many sensor combinations are available including chlorine and ammonia for water treatment applications and also methane, oxygen and hydrogen sulfite.
