These spring loaded high temperature magnet thermocouples are versatile and robust. They provide excellent surface temperature measurement between the range of -10°C to +480°C for types K, J and N (400°C max. for type T). Supplied with stainless steel braided fibreglass insulated cable, these sensors are perfect for applications where very close contact to the surface is critical whilst maintaining the durability to withstand high temperatures. There is also an anti-chafe spring which relieves strain on the cable when removing the magnet from surfaces, although it is not recommended to pull on the cable to remove the sensor after use. Magnet size: 25.4mm diameter x 15.9mm thick.
