TKK’S RAKO research project summary of the HCS measurement technology and accuracy

Summary of Vahanen Rakennusfysiikka Oy's statement on the comparison of Humi 2 sensors with borehole measuring.

Humi 2 sensor for monitoring structural drying and long-term moisture

An adjustable foot that can be pre-adjusted to the correct depth before casting and, if necessary, fine-tuned to the surface.
Suitable for both new constructions and renovation, and for casting thicknesses of 50–240 mm.
For humidity measurement, the sensor is positioned at the correct depth (RT
14-10984, with one-way drying slabs at 40 % of total thickness and with two-way drying slabs at 20 %).
Measurement accuracy: + / - 2.5 RH %
Measurement accuracy + / - 0.3 °C
Installation depth: max. 10 cm
