HCD-S – Humidity and Temperature Probe

HCD-S – Humidity and Temperature Probe

The HCD-S digital probe is characterized by its high performance. Very low current consumption, the highest accuracy, and measurement results within 50 ms (electronics) are its outstanding features. This is due to the new AirChip4000, which together with the new HYGROMER® HT-1 sensor forms a powerful combination.
