DOL 119 CO2 Sensor

A New Generation CO2 Sensor that Withstands High-Pressure Cleaning

DOL 119 CO2 sensor measures the carbon dioxide level and air quality in livestock houses. The sensor ensures that the broilers enjoy optimal climate conditions and avoiding a higher FCR and increased mortality.

At dol-sensors we constantly improve our products due to our customers’ requests. Therefor we designed a new and life-time improved CO2 sensor to replace the DOL 19. Our new CO2 sensor DOL 119 is IP 67 protected, which means that it is waterproof withstanding high-pressure cleaning. We made sure that the replacement of your old DOL 19’s is easily made.

DOL 119 is robust and well-suited for the harsh conditions in livestock houses. Since the sensor is placed in the middle of the barn and not on the wall as many other CO2 sensors, it measures the level of CO2 where it is most accurate. Therefor delivers a reliable and accurate measurement where it effects actual animal air quality.

The sensor can be customized for any farm management system in the world which makes it unique on the market.

Why should you monitor CO2 level in livestock?

High levels of carbon dioxide in livestock houses results in poorer animal welfare, higher FCR and increased animal mortality. Therefor it is important to measure the CO2 level and act if the level is too high.
