Type 915 versions are the 90° angled probes matched to the RTC-156 and RTC-157 calibrators, so sensors under test still fit alongside them in the well.\u003c\/p\u003e\n\u003cp\u003eThis B-size 915 probe has a 6.35 mm (1\/4 in) INCONEL 600 sheath, a 179 mm stem and 110 mm minimum immersion depth. Resistance is converted to temperature on the ITS-90 scale with probe-specific coefficients, and the H option adds an ISO 17025 accredited certificate calibrated over the standard -45 to 155 °C span.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePt100 reference sensor, α = 0.00385\u003c\/li\u003e\n\u003cli\u003eType 915 range: -65 to 160 °C\u003c\/li\u003e\n\u003cli\u003eRepeatability 0.002 °C (0.004 °F)\u003c\/li\u003e\n\u003cli\u003eHysteresis 0.01 °C at 0 °C\u003c\/li\u003e\n\u003cli\u003eLong-term stability typically 0.014 °C at 0 °C\u003c\/li\u003e\n\u003cli\u003e90° angled sheath clears sensors under test\u003c\/li\u003e\n\u003cli\u003eLEMO connector with built-in memory chip\u003c\/li\u003e\n\u003cli\u003eISO 17025 accredited certificate included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReference standard for dry-block, bath and handheld calibrators\u003c\/li\u003e\n\u003cli\u003eCustody transfer temperature verification\u003c\/li\u003e\n\u003cli\u003eWorking standard in calibration laboratories\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAmetek Jofra STS200B915EH Reference Probe Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor\u003c\/th\u003e\n\u003ctd\u003ePt100, α = 0.00385\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType 915 range\u003c\/th\u003e\n\u003ctd\u003e-65 to 160 °C (-85 to 320 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard calibration range\u003c\/th\u003e\n\u003ctd\u003e-45 to 155 °C (ITS-90)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRepeatability\u003c\/th\u003e\n\u003ctd\u003e0.002 °C (0.004 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHysteresis\u003c\/th\u003e\n\u003ctd\u003e0.01 °C at 0 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLong-term stability\u003c\/th\u003e\n\u003ctd\u003etyp. 0.014 °C at 0 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSelf-heating\u003c\/th\u003e\n\u003ctd\u003e0.06 °C\/mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSheath diameter (B)\u003c\/th\u003e\n\u003ctd\u003e6.35 mm (1\/4 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStem length\u003c\/th\u003e\n\u003ctd\u003e179 mm, 90° angled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum immersion depth\u003c\/th\u003e\n\u003ctd\u003e110 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResponse time\u003c\/th\u003e\n\u003ctd\u003eτ50% 18 s, τ90% 44 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnection\u003c\/th\u003e\n\u003ctd\u003eLEMO plug with memory, 0.5 m cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMedia compatibility\u003c\/th\u003e\n\u003ctd\u003eINCONEL 600\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnector and cable operating range\u003c\/th\u003e\n\u003ctd\u003e-20 to 70 °C, IP50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/www.ametekcalibration.com\/products\/temperature\/reference-temperature-sensors\/sts-reference-sensors\" target=\"_blank\" rel=\"noopener\"\u003eSTS Reference Sensors on ametekcalibration.com\u003c\/a\u003e.\u003c\/p\u003e","brand":"Ametek Jofra","offers":[{"title":"Default Title","offer_id":67777208680635,"sku":"IMM_84625644","price":1037.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/ametek-jofra-sts200b915eh.jpg?v=1792557346","url":"https:\/\/na.indomultimeter.net\/products\/ametek-jofra-sts200b915eh-reference-probe-pt100-90-angled-65-to-160-c","provider":"Indo Multimeter","version":"1.0","type":"link"}
