The ordering code decodes as follows: STS100 designates the Pt100 reference probe covering -150 to 650°C, B the 6.35 mm (0.25 in) probe diameter, 500 the 500 mm (19.7 in) straight probe length, A the 0.5 m (1.6 ft) cable with LEMO connectors, and H the ISO 17025 accredited calibration certificate (specified -45 to 650°C).\u003c\/p\u003e\u003cp\u003eSTS probes are engineered for stability: they undergo long-term burn-in up to 650°C so drift stays low even after sustained high-temperature exposure, and their compact size, fast response and small required immersion depth suit dry-block calibrators where well space is limited. Combined with an AMETEK RTC temperature calibrator, the STS reference sensor forms a system accurate to +\/-0.04°C. This performance has made STS sensors the working standard in many national laboratories worldwide, while the direct-readout design also allows use in custody-transfer applications where high accuracy translates directly into money.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePt100 reference sensor, -150°C to 650°C temperature range\u003c\/li\u003e\n\u003cli\u003e6.35 mm (0.25 in) probe diameter, 500 mm (19.7 in) straight stem\u003c\/li\u003e\n\u003cli\u003e0.5 m (1.6 ft) cable with LEMO connectors (option A)\u003c\/li\u003e\n\u003cli\u003eISO 17025 accredited calibration certificate, -45 to 650°C (option H)\u003c\/li\u003e\n\u003cli\u003eSystem accuracy of +\/-0.04°C when combined with RTC calibrators\u003c\/li\u003e\n\u003cli\u003eLong-term burn-in up to 650°C for specified low drift\u003c\/li\u003e\n\u003cli\u003eFast response and low immersion depth for dry-block calibrators\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReference standard for dry-block, bath and hand-held temperature calibrators\u003c\/li\u003e\n\u003cli\u003eCustody-transfer temperature measurement where accuracy affects payment\u003c\/li\u003e\n\u003cli\u003eCalibration and verification of industrial temperature sensors and thermometers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAmetek Jofra STS100B500AH Reference Probe Technical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor type\u003c\/th\u003e\n\u003ctd\u003ePt100 reference temperature probe (STS100 series)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature range\u003c\/th\u003e\n\u003ctd\u003e-150°C to 650°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProbe diameter\u003c\/th\u003e\n\u003ctd\u003e6.35 mm \/ 0.25 in (option B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProbe shape \/ length\u003c\/th\u003e\n\u003ctd\u003eStraight probe, 500 mm \/ 19.7 in (option 500)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCable\u003c\/th\u003e\n\u003ctd\u003e0.5 m \/ 1.6 ft with LEMO connectors (option A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCertificate\u003c\/th\u003e\n\u003ctd\u003eISO 17025 accredited, -45°C to 650°C (option H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSystem accuracy\u003c\/th\u003e\n\u003ctd\u003e+\/-0.04°C when combined with RTC temperature calibrators\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBurn-in\u003c\/th\u003e\n\u003ctd\u003eLong-term burn-in up to 650°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDesign strengths\u003c\/th\u003e\n\u003ctd\u003eFast response, low immersion depth, compact size, low drift\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eAMETEK Denmark A\/S (Jofra), Allerod, Denmark\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/www.ametekcalibration.com\/products\/temperature\/reference-temperature-sensors\/sts-reference-sensors\" target=\"_blank\" rel=\"noopener\"\u003eAMETEK STS Series Reference Sensors product page\u003c\/a\u003e\u003c\/p\u003e","brand":"Ametek Jofra","offers":[{"title":"Default Title","offer_id":67776159023291,"sku":"IMM_48441221","price":1073.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/ametek-jofra-sts100b500ah.jpg?v=1792552079","url":"https:\/\/na.indomultimeter.net\/products\/ametek-jofra-sts100b500ah-reference-probe-150-to-650-c","provider":"Indo Multimeter","version":"1.0","type":"link"}
