SKU: SF-SEN-00251

36" high temperature Type-K Thermocouple with glass braid insulation.

SKU: AF-270

A Type-K thermocouple with fiberglass braid insulation, rated to 500°C — far beyond the ~200°C limit of standard vinyl-insulated thermocouples. The bare bead probe design is suited to measuring both air and surface temperatures in high-heat environments such as ovens, kilns, heaters, and industri...

SKU: AF-3245

Thermocouples are best used for measuring temperatures that can go above 100°C. This is a bare wires stainless-steel tip probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200°C, this one uses a fiberglass braid so...

SKU: SF-SEN-13715

This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a ‘cold’ one). Once this is achieved, a voltage potential is ...

SKU: SF-COM-15082

Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature dif...
