Description
The HDH transmitters are specially designed for measuring and controlling the carbon dioxide concentration (CO2) and temperature in indoor spaces. These advanced sensors provide accurate measurements, essential for applications in ventilation and air handling systems, where air quality and temperature are crucial.
With the ABCLogic™ self-calibration method, potential long-term drift of the sensors is eliminated, ensuring reliable and stable performance over the long term. In addition, the controller settings and option limits can be easily adjusted using the ML-SER tool, guaranteeing flexibility and convenience.
features
- Measurement of CO2 concentration and temperature for precise indoor air quality control.
- ABCLogic™ self-calibration for accurate measurements without long-term drift.
- Settings and option limits adjustable via the ML-SER tool for flexible configuration.
- Ideal for ventilation and air handling systems in commercial and industrial environments.
The HDH transmitters offer reliable measurement and control solutions for optimal control of air quality and temperature, with a long service life and minimal maintenance requirements.
