850°C Working standard PRTs

This new product combines our high temperature RTD probe technique with our special reference grade RTD elements. WSP850 series have similar accuracy and long-term stability of SSP850 secondary standard PRTs. This working standard PRT has upper limit up to 850°C and resistance drift at triple point of water less than 0.030°C after long-term test at 850°C for 500 hours. WSP850 PRT is designed for industrial environments to withstand mechanical shock.
