MODEL C810 (Pt/Pd thermocouple for secondary standard) C810 is a standard thermocouple manufactured with materials of high purity platinum (+ pole) and palladium (- pole) which has been commercialized under the guidance of National Metrology Institute of Japan, AIST. It is more stability in measuring high temperature than the thermocouple manufactured with metal (R, S, B) which has been conformed to JIS C1602 (IEC60584). Materials: Wire diameter: Wire length: Protecting tube: •C810 is designed as a standard thermocouple used for secondary standard at freezing point of silver and copper. The protecting tube is also easily removable. ■ MODELS Calibration point AG: Silver CU: Copper GENERAL SPECIFICATIONS Cu (1084.62°C)* + --- Platinum (Purity of 99.999%) — --- Palladium (Purity of 99.99%) 00.5mm 2800mm Quartz 0 7mm x 900mm Reference junction: 04.8mm x 300mm with SUS316 Protecting tube External lead wire: Copper lead wire 2m with gold chip * Conformed to JCT21306 specific application documents (contact type thermometer) issued by National Institute of Technology and Evaluation.

MODEL C850 (Au/Pt thermocouple) C850 is a standard thermocouple manufactured with materials of high purity gold (+ pole) and platinum (- pole) which has been commercialized by collaborative research with professor Goto from College of Engineering in Tamagawa University. It has smaller electromotive force drift and less uncertainty when measuring high temperature comparing to the thermocouple manufactured with metal (R, S, B) which has been conformed to JIS C1602 (IEC60584). • Long term stability is 15mK (960°C /500hr). It enables lower cost than platinum resistance thermometer and higher accurate...

MODELS C800-15(S TYPE) C800-35(R TYPE) C800-65(B TYPE) These sensors are standard sensors with measuring range from 200 to 1554 °C which constructed with a stem structure of a high purity alumina ceramic protecting tube recrystallized. •Strictly selected bare thermocouple, unique cleaning and heat treatment techniques realized more stable and high accurate sensors. •The thermocouples feature high heat conductivity and excellent stability under an oxidation-reduction atmosphere as protecting tube and insulation tube are made of high purity recrystallized alumina. •Standard thermocouples are excluded...
