The GD231 FREON Sensor is used for diffusion sensing applications. These are applications in which the sensor continuously monitors that part of the environment with which it is in contact and the gas diffuses through the sensor’s optical path. It could also raise audible and/or visual alarms when the concentration reaches a predetermined level. Alternatively, the GD231 FREON Sensor may operate as a stand alone unit using the LED array to indicate the approximate concentration of gas present and the internal relays to generate concentration alarms.
