Thermocouple Wire

(Click on images to enlarge) 

Type K thermocouple wire for general purpose temperature measurements in concrete, asphalt and ambient air
The wires are twisted together at one end and a plug (Part No. 4559764 - Type `K` mini T couple) are attached to the other end of the wire.
Temperature buttons (i-buttons)
Programmable to measure temperatures within a pavement structure or ambient air.
Thermochron i-buttons temperature / humidity buttons
Heaters
Heating test section In South Africa the heaters used typically consist of a panel of 6 heaters (3 on each side of the test section) with 2 x 1 600 Watt elements per heater. With these heaters pavement temperatures of up to 80°C can be achieved inside the environmental chamber with ambient outside temperatures of down to 5°C.
Temperature Data acquisition. (TC-2095) National Instruments
Connecting thermocouples. Plug in the thermocouples.
