DOL 139 is a smart 3-in-1 sensor combining measurement of both relative humidity, temperature, and carbon dioxide (CO2).
Save Time and Money Using the DOL 139
Since DOL 139 measures 3 important elements of the environment; humidity, temperature, and CO2, it makes for an easier installation, less maintenance and a more cost-effective solution. No need for multiple sensors when you can use a single sensor to measure 3 elements.
A Strong Durable Sensor with a Long Lifetime
The sensor is specially designed to withstand the harsh conditions in livestock houses and industrial environments.
Withstands High-Pressure Cleaning
DOL 139 is protected by a sturdy casing and behind a carefully selected filter. It is supplied with a protection cap for protection of the sensor during washing and disinfection, even during high-pressure cleaning.
It is easy to replace DOL 19 or DOL 119 CO2 sensors as well as DOL 104 humidity sensor and DOL 114 humidity and temperature sensor with a DOL 139. The DOL 139 will then serve as the only sensor needed for measuring humidity, temperature, and CO2.
