The Vaisala Surface Patrol DSP100 with display is a mobile temperature sensor for the detection of possible negative temperatures of the pavement.

It comprises an infrared sensor for noncontact measurement of the temperature of the floor surface and also measure the temperature of the air. Easy to use, this is a particularly valuable tool for any type of operator, ranging from large organizations such as transport services to smaller companies only a few trucks.
