DOL 139 Humidity, Temperature, and CO2 Sensor

DOL 139 is a 3-in-1 sensor for livestock houses

DOL 139 is an intelligent 3-in-1 sensor combining measurement of relative humidity, temperature and carbon dioxide (CO2).

Save time and money with DOL 139

Because DOL 139 measures 3 important environmental parameters — humidity, temperature and CO2 — it simplifies installation, reduces maintenance costs and offers a more cost-effective solution. There is no need for multiple sensors when one sensor can measure all 3 parameters.

A robust, reliable sensor with a long service life

The sensor is specially designed to withstand harsh conditions in livestock houses and industrial environments.

Withstands high-pressure cleaning

DOL 139 is protected by a robust housing and a carefully selected filter. It comes with a protective cap to shield the sensor during washing and disinfection, including high-pressure cleaning.

Easy replacement

It is easy to replace DOL 19 or DOL 119 CO2 Sensors, as well as the DOL 104 Humidity Sensor and DOL 114 Humidity and Temperature Sensor with DOL 139. DOL 139 then serves as the only sensor needed to measure humidity, temperature and CO2.Read more about dol-sensors climate sensors here
