The mid-range 878-425 model spans 33 C to 425 C, heats quickly to temperature, and holds +\/-0.20 C display accuracy at 33 C and 425 C with 30-minute stability of +\/-0.005 C at 100 C and +\/-0.015 C at 425 C. Dual-zone temperature control is standard, and each unit ships with an ISO 17025 accredited calibration certificate including stability, radial and axial uniformity data.\u003c\/p\u003e\u003cp\u003eThe series adds automation that older dry wells lack. A self-calibration routine recalibrates the internal control sensor against an external reference automatically, removing long-term drift from the accuracy budget, and the well can be controlled to set point from either the internal sensor or an external reference PRT. A large color touchscreen drives the interface, Wi-Fi and Bluetooth handle connectivity, and this version is fitted with insert D and a 220 V mains configuration for labs running on 230 V supplies.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReference dry well covering 33 C to 425 C\u003c\/li\u003e\n\u003cli\u003eDisplay accuracy of +\/-0.20 C at 33 C and 425 C\u003c\/li\u003e\n\u003cli\u003eStability of +\/-0.005 C at 100 C and +\/-0.015 C at 425 C (30 min)\u003c\/li\u003e\n\u003cli\u003eDual-zone temperature control for excellent uniformity\u003c\/li\u003e\n\u003cli\u003eBuilt-in self-calibration of the control sensor using an external reference\u003c\/li\u003e\n\u003cli\u003eSet point control by internal sensor or external reference PRT\u003c\/li\u003e\n\u003cli\u003eColor touchscreen with Wi-Fi and Bluetooth connectivity\u003c\/li\u003e\n\u003cli\u003eShips with ISO 17025 accredited calibration and data\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCalibrating RTDs and thermocouples in the lab or on site\u003c\/li\u003e\n\u003cli\u003eVerification of temperature transmitters and sensor assemblies\u003c\/li\u003e\n\u003cli\u003eReference heat source for secondary standards work up to 425 C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAdditel ADT878-425-D-220V Temperature Calibrator Technical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eADT878-425-D-220V (Additel 878 series)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature range at 23 C ambient\u003c\/th\u003e\n\u003ctd\u003e33 C to 425 C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInsert\u003c\/th\u003e\n\u003ctd\u003eInsert D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplay accuracy\u003c\/th\u003e\n\u003ctd\u003e+\/-0.20 C at full range (33 C and 425 C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStability (30 min)\u003c\/th\u003e\n\u003ctd\u003e+\/-0.005 C at 100 C, +\/-0.010 C at 225 C, +\/-0.015 C at 425 C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature control\u003c\/th\u003e\n\u003ctd\u003eDual-zone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eControl sensor self-calibration\u003c\/th\u003e\n\u003ctd\u003eBuilt-in, automated against external reference\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSet point control\u003c\/th\u003e\n\u003ctd\u003eInternal sensor or external reference PRT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplay\u003c\/th\u003e\n\u003ctd\u003eColor touch screen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnectivity\u003c\/th\u003e\n\u003ctd\u003eWi-Fi and Bluetooth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMains\u003c\/th\u003e\n\u003ctd\u003e220 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCalibration included\u003c\/th\u003e\n\u003ctd\u003eISO 17025 accredited with data\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/additel.com\/product-detail.html\/878-dry-well-temperature-calibrator\" target=\"_blank\" rel=\"noopener\"\u003eAdditel 878 Reference Dry Well Calibrator on additel.com\u003c\/a\u003e\u003c\/p\u003e","brand":"Additel","offers":[{"title":"Default Title","offer_id":67776243237051,"sku":"IMM_83414842","price":6068.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/additel-adt878-425-d-220v-600x600-1.jpg?v=1792552285","url":"https:\/\/na.indomultimeter.net\/products\/additel-adt878-425-d-220v-temperature-calibrator-33-to-425-c-insert-d","provider":"Indo Multimeter","version":"1.0","type":"link"}
