| | | Solid State - Carbon Dioxide Sensor | | |
| | | |
| | | Our new carbon dioxide sensor, still being improved, is the first result of years of research into potentiometric gas sensors. Operating as a gas ion selective electrode (ISE), the sensor has an easy interface, and is supplied in our D Family size and in the future a 2025 button cell will become available. This sensor is emerging from development, and is now ready for field trials. Specifications may change. | | |
