Humidity and temperature transmitters are used in metro stations to control ventilation and air conditioning. The control of air moisture levels provides a comfortable environment for passengers, optimizes HVAC equipment energy consumption, and maintains the integrity of the equipment.

The Vaisala INTERCAP® and HUMICAP® Humidity and Temperature transmitters provide accurate and stable measurements with minimal maintenance requirements. Vaisala humidity sensors fully recover from condensation without compromising the performance. This is important especially in high humidity climates, where condensation is likely to occur.
