Description
DOL 139 is a digital sensor that measures relative humidity, temperature and carbon dioxide (CO2) levels. The sensor is mounted on walls or ventilation ducts and is designed for use in farms, industrial workshops, offices, educational institutions and other premises where it is important to maintain air quality and an optimal climate. It operates in the following measurement range: CO₂: 0–5000 ppm, accuracy ±50 ppm; Temperature: -20 °C to +50 °C, accuracy ±0.5 °C; Humidity: 0–100 % RH, accuracy ±2 %. The DOL 139 sensor is compatible with ventilation and air conditioning systems, microclimate controllers on farms and in greenhouses. Monitor CO₂, temperature and humidity with ease – choose the DOL 139 today!Benefits and warranty

DOL 139 Smart 3-in-1 Sensor (Humidity, Temperature & CO2)
The DOL 139 is a sophisticated, all-in-one environmental monitoring solution designed for precision agriculture and demanding industrial applications. By integrating relative humidity, temperature, and carbon dioxide (CO2) sensing into a single, high-fidelity unit, the DOL 139 streamlines climate management. This 3-in-1 approach eliminates the need for redundant sensors, significantly reducing hardware costs, simplifying installation, and providing a unified data stream for livestock welfare and performance optimization.

Durability for Extreme Environments
Specifically engineered to survive the corrosive atmospheres of intensive livestock housing, the DOL 139 features a rugged housing and specialized filters that protect delicate sensing membranes from ammonia, dust, and moisture saturation. It is designed as a direct "plug-and-play" upgrade for existing installations using DOL 19/119 (CO2), DOL 104 (Humidity), or DOL 114 (T+RH) sensors. Upgrading to the DOL 139 not only saves money on procurement but also drastically lowers long-term maintenance cycles by unifying the farm's sensing grid.
Installation and Maintenance Strategies
For representative air quality data, the DOL 139 must be installed at the animals' level (typically $1.5 - 2$ meters above the floor). Avoid stagnant "dead zones" or locations directly adjacent to air inlets or heaters. A key strategic feature is the industrial-grade protection cap. During high-pressure washdowns or disinfection fogging, the sensor does not need to be removed; simply secure the protection cap to shield the sensor head from water jets and chemical agents, protecting your investment from operational damage.
Strategic Comparison Table
| Strategic Feature | Single DOL 139 Sensor | Standard 3-Sensor Setup |
|---|---|---|
| Deployment Cost | Low (Single cable/mounting point) | High (Triple wiring and labor) |
| Cleaning Resistance | Superior (Single protection cap) | Complex (Requires individual care) |
| System Maintenance | Simplified (Unified diagnostics) | High (Multiple failure points) |
| Data Synergy | Perfect (Synchronized measurements) | Variable (Sensor-to-sensor drift) |
DOL 139 — the professional standard for integrated climate control.
