500°C Secondary Standard PRTs

Model SSP500 series secondary standard PRTs use 99.999% pure platinum wire as sensing elements to assure excellent stability. Because the platinum wire is supported by a special ceramic material with no strain, the PRTs can withstand rough environment and thermal shock.
