A Temperature, Humidity, and CO2 Controller EMS KR-751 is a smart device that measures and controls three essential environmental parameters: temperature (°C), relative humidity (%RH), and CO2 concentration (ppm).
It is widely used in greenhouses, cleanrooms, cold storage facilities, manufacturing plants, offices, and smart buildings to maintain stable, safe, and energy-efficient conditions.

Key Features of the Temperature, Humidity, and CO2 Controller

- High measurement accuracy using premium, low-drift sensors.
- Real-time display: LCD/LED screen shows all parameters simultaneously.
- Customizable thresholds: Independent alarm and control settings for each parameter.
- Automatic control integration: Operates ventilation fans, HVAC systems, humidifiers, or CO2 dosing units.
- Multiple output options: Relay on/off, analog output (0–10V, 4–20mA), Modbus RTU/TCP communication.
- Durable construction: Reliable operation even in harsh or high-humidity environments.

Applications of the Temperature, Humidity, and CO2 Controller

- Greenhouses - Optimize plant growth by maintaining ideal environmental conditions.
- Cleanrooms and laboratories - Meet strict environmental and safety requirements.
- Cold storage for food and pharmaceuticals – Preserve product freshness and quality.
- Industrial production lines - Improve product consistency and protect equipment.
- Commercial buildings and offices - Enhance indoor air quality and occupant comfort.
