  Simple and Effective

The Dynagard 25 Series accurately measures CO2 levels. The unit offers a local display, a horn / strobe, and a linear 4-20 mA output. The Dynagard 25 Series offers a safe and reliable gas warning system.

Alarm Points

Each alarm can be adjusted separately. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be set to over range / under range, latching / non-latching, or resettable / non-resettable.

Alarm relays
 The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns.

  IR 24 Detection Principle: Infrared Light
 Since carbon dioxide (CO2) absorbs light in the infrared spectral range, the NDIR method used in the GfG sensor can measure the carbon dioxide concentration precisely and reliably. Infrared light is sent through the sensor chamber. Carbon dioxide absorbs a part of this light in a narrow spectral range, and the remaining light is measured at the detector. The difference between the light sent and received is proportional to the gas concentration. Water vapor or other gases that can be present in the sensor chamber do not affect the light absorption in this spectrum band.
