IR-SENSORS
|
||||||||||
| Our IR sensors are split into two separate groups as OEM and industrial sensors. The components measured are carbon dioxide (CO2) and methane (CH4). The measurements are based on the principle of light absorption in the infrared range, known as non-dispersive infrared (NDIR) technology. |

OEM Sensors
|
|
|||||||||
| Compact, low-cost sensors for carbon dioxide and methane designed for OEM applications. Available with or without housing. Many measuring ranges and output levels as standard. Single channel. Tailor-made solutions possible. Outputs for display, analogue and digital ouputs together with control of external pump and solenoid valve are possible. | ||||||||||

Industrial Sensors
|
|
|||||||||
| Carbon dioxide and methane sensors for stationary installation. Fitted in a plastic IP54 housing. Available in many ranges and with various output configurations as diffusion or through flow sensor. Single channel available. Internal pump, solenoid valve and display available as options. | ||||||||||
