MetSalt is a unique low-power embedded road sensor for accurate measuring of the road temperature and even more accurate detection of the freezing point. It is equipped with an external temperature probe which enables temperature measurement in a specific depth.
Two part housing and removable electronics allow for an easy maintenance.
External Temperature Probe
MetSalt is equipped with an external temperature probe which enables accurate detection of both surface and deep road temperatures.
Low Power Consumption
A smart measurement algorithm allows for a low power consumption.
Freezing Point Detection
Sensor is flush mounted in the pavement and performs a continuous cycle of freezing point detection.
