The PC option adds an external reference input plus a two-channel readout for RTDs and thermocouples, along with mA\/VDC measurement and switch testing, turning the dry well into a complete temperature and process calibration station.\u003c\/p\u003e\n\u003cp\u003eThe 425 model covers 33 to 425 °C at 23 °C ambient (per the 2026 datasheet revision) with ±0.2 °C display accuracy across the full range and stability of ±0.010 °C at 100 °C. An automated self-calibration routine aligns the internal control sensor to an external reference, keeping long-term drift out of your uncertainty budget.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReference dry-well range 33 to 425 °C (at 23 °C ambient)\u003c\/li\u003e\n\u003cli\u003eDisplay accuracy ±0.2 °C at full range\u003c\/li\u003e\n\u003cli\u003eStability ±0.010 °C at 100 °C; ±0.015 °C at 225 °C; ±0.020 °C at 425 °C (30 min)\u003c\/li\u003e\n\u003cli\u003eProcess Calibrator option: RTD and 2 TC channels, mA\/VDC, switch test\u003c\/li\u003e\n\u003cli\u003eAutomated self-calibration of internal control sensor\u003c\/li\u003e\n\u003cli\u003eHeats 23 to 425 °C in 15 minutes\u003c\/li\u003e\n\u003cli\u003eExternal reference input for traceable comparison\u003c\/li\u003e\n\u003cli\u003e220 V AC power (model ADT878PC-425-NO-220V)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReference calibration of RTDs and thermocouples\u003c\/li\u003e\n\u003cli\u003eCalibration of process sensors and temperature switches\u003c\/li\u003e\n\u003cli\u003eLaboratory temperature reference and comparison checks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAdditel ADT878PC-425-NO-220V Temperature Calibrator Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\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\u003eDisplay accuracy\u003c\/th\u003e\n\u003ctd\u003e±0.2 °C at full range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStability (30 min)\u003c\/th\u003e\n\u003ctd\u003e±0.010 °C at 100 °C; ±0.015 °C at 225 °C; ±0.020 °C at 425 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRadial uniformity\u003c\/th\u003e\n\u003ctd\u003e±0.025 °C at 100 °C; ±0.030 °C at 225 °C; ±0.040 °C at 425 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAxial uniformity\u003c\/th\u003e\n\u003ctd\u003e±0.10 °C at 100 °C; ±0.15 °C at 225 °C; ±0.25 °C at 425 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExternal reference sensor accuracy\u003c\/th\u003e\n\u003ctd\u003e±0.01 °C at 100 °C; ±0.02 °C at 425 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeating time\u003c\/th\u003e\n\u003ctd\u003e15 min (23 to 425 °C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProcess calibrator inputs\u003c\/th\u003e\n\u003ctd\u003eExternal RTD reference, 2 TC channels, mA\/VDC, switch test\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInsert \/ well diameter\u003c\/th\u003e\n\u003ctd\u003eInsert OD 31.9 mm (1.26 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEnvironmental\u003c\/th\u003e\n\u003ctd\u003e8 to 38 °C guaranteed accuracy; 0 to 50 °C operating, 0-90% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage temperature\u003c\/th\u003e\n\u003ctd\u003e-20 to 60 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e220 V AC (ADT878PC-425-NO-220V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/www.additel.com\/download\/datasheet\/878\/878_Reference_Dry_Well_Calibrators.pdf\" target=\"_blank\" rel=\"noopener\"\u003eADT878 datasheet on additel.com\u003c\/a\u003e.\u003c\/p\u003e","brand":"Additel","offers":[{"title":"Default Title","offer_id":67777128857787,"sku":"IMM_13793114","price":7007.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/additel-adt878pc-425-no-220v-600x600-1.jpg?v=1792556863","url":"https:\/\/na.indomultimeter.net\/products\/additel-adt878pc-425-no-220v-temperature-calibrator-33-to-425-c-reference-dry-well-with-process-calibrator-option","provider":"Indo Multimeter","version":"1.0","type":"link"}
