Watlow provides more than 80 years of manufacturing, research and quality for your temperature sensing needs. A tremendous stock of general application, mineral insulated, base and noble metal thermocouples are available. Hundreds of thermocouples are available as part of our Rapid Ship sensor program. These sensors are shipped directly to you in one or two days. Watlow also has three new surface temperature sensors. The MICROCOIL, radio frequency thermocouple probe and true surface thermocouples all incorporate isothermal physical principles to achieve superior surface temperature measurement. The isothermal design provides accurate sensing because the areas of the temperature sensor that are exposed to normal process variances are positioned outside the thermal gradient.
