The DOL 119 CO₂ sensor measures carbon dioxide levels in livestock barns. This sensor ensures that broilers enjoy optimal climatic conditions, helping to prevent CO2 spikes and increased mortality rates.
At dol-sensors, we are constantly improving our products to meet our customers’ needs. As a result, we have designed a new product with an extended service life. It is a replacement for the DOL 19 CO₂ sensor. Our new DOL 119 CO₂ sensor is IP67-rated, meaning it is waterproof and can withstand high-pressure washing. We have made it easy to replace the older DOL 19 model.
The DOL 119 is rugged and well-suited for the harsh conditions found in livestock barns. Unlike many other CO₂ sensors, it is not mounted on a wall but is positioned in the center of the barn, allowing for the most accurate measurement of CO₂ levels. This ensures highly reliable and precise measurements in the very areas that affect the actual air quality for the animals.
The sensor can be customized to integrate with any farm management system worldwide, making it truly one-of-a-kind on the market.
- Easily replacement of DOL 19
- Can be customized for any farm management system
- Reliable and accurate monitoring of the CO2 level
- CO2 measurement time improved by over 100%
