The AVI-GAS gas meter is intended for monitoring the composition of the atmosphere in fruit and vegetable storage facilities. The measuring range is 0-25% vol. for oxygen and 0-10% vol. for carbon dioxide. Optionally, the device can be extended with relative humidity measurement.
The device uses a long-life electrochemical oxygen sensor and an NDIR infrared carbon dioxide sensor. It is equipped with its own diaphragm pump and a built-in battery, allowing operation without connection to mains power.
Functional features
- Selective measurement of oxygen and carbon dioxide.
- Negligible influence of other gases on the device indications.
- Automatic carbon dioxide zeroing and oxygen calibration.
- Very long carbon dioxide sensor lifetime — over 10 years.
- Long oxygen sensor lifetime — approx. 4 years in atmospheric air.
- Large, readable display.
- Small dimensions and low weight.
- Operation without connection to the electrical mains.
