Profile: Advanced Sensing Products (ASP) is a manufacturer of temperature sensors. Since its inception in 1997, ASP has developed proprietary technology to produce temperature sensors with qualities and temperature ranges unsurpassed in the industry, with a focus on secondary standard platinum resistance thermometers (PRTs), working standard PRTs, and precision industrial resistance temperature detectors (RTDs). In addition, ASP also offers temperature sensor calibration services and it is capable of providing certificates that are NIST traceable. We produce all elements for our temperature sensors and probes, which ensures superior stability and repeatability to be assembled in the RTD probes. This gives us a total control over our product quality. Our RTDs have a temperature range from -200 °C to 1,100 °C. The RTDs are used in industrial as well as laboratory metrology applications. The products and technology of ASP are wildly applied in libratory metrology, instrumentation, industrial process control and measurement.
