The CTC-660 spans 28 to 660 °C with an accuracy of ±0.85 °C using the internal reference sensor, improving to ±0.45 °C when the optional external STS-120-A-966 reference sensor is fitted. MVI mains power variance immunity keeps the block stable even when supply voltage fluctuates in industrial environments.\u003c\/p\u003e\n\u003cp\u003eFast calibration is the priority: heating from 23 to 660 °C takes 18 minutes, time to stability is about 5 minutes, and set, preset, auto-step and switch test functions handle quick routines. The informative color display, USB 2.0 interface with JofraCal calibration software, interchangeable inserts and the heat shield supplied as standard round out the package for workshop duties.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature range 28 to 660 °C\u003c\/li\u003e\n\u003cli\u003e±0.85 °C accuracy with internal reference sensor\u003c\/li\u003e\n\u003cli\u003e±0.45 °C accuracy with external STS-120-A-966 reference sensor\u003c\/li\u003e\n\u003cli\u003e±0.08 °C stability, 0.01 °C resolution\u003c\/li\u003e\n\u003cli\u003eHeats 23 to 660 °C in 18 minutes\u003c\/li\u003e\n\u003cli\u003eMVI mains power variance immunity\u003c\/li\u003e\n\u003cli\u003eSwitch test, preset and auto-step functions (up to 12 steps)\u003c\/li\u003e\n\u003cli\u003eUSB 2.0 interface with JofraCal calibration software\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCalibration of RTDs, thermocouples and temperature switches\u003c\/li\u003e\n\u003cli\u003eInstrument shop verification of temperature sensors\u003c\/li\u003e\n\u003cli\u003eOn-site calibration of process temperature instrumentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCTC dry-block calibrator\u003c\/li\u003e\n\u003cli\u003eMains power cable\u003c\/li\u003e\n\u003cli\u003eTraceable certificate of temperature performance\u003c\/li\u003e\n\u003cli\u003eTool for insertion tubes\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eTest cables (1 x red, 1 x black)\u003c\/li\u003e\n\u003cli\u003eUSB cable\u003c\/li\u003e\n\u003cli\u003eJofraCal calibration software\u003c\/li\u003e\n\u003cli\u003eHeat shield\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAmetek Jofra CTC-660 Dry Block Calibrator Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature range\u003c\/th\u003e\n\u003ctd\u003e28 to 660 °C (82 to 1220 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy, internal reference\u003c\/th\u003e\n\u003ctd\u003e±0.85 °C at 660 °C; ±0.65 °C at 200 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy, external reference\u003c\/th\u003e\n\u003ctd\u003e±0.45 °C at 660 °C; ±0.40 °C at 200 °C (STS-120-A-966)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStability\u003c\/th\u003e\n\u003ctd\u003e±0.08 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd\u003e0.01 °C (1, 0.1 or 0.01 selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRadial homogeneity\u003c\/th\u003e\n\u003ctd\u003e0.1 °C at 660 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeating time\u003c\/th\u003e\n\u003ctd\u003e23 to 660 °C in 18 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCooling time\u003c\/th\u003e\n\u003ctd\u003e660 to 100 °C in 39 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWell diameter\u003c\/th\u003e\n\u003ctd\u003e26 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImmersion depth\u003c\/th\u003e\n\u003ctd\u003e115 mm incl. insulation plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e6.1 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e248 x 148 x 305 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMains power\u003c\/th\u003e\n\u003ctd\u003e115 V (90-127) or 230 V (180-254) VAC, max 1150 VA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInterface\u003c\/th\u003e\n\u003ctd\u003eUSB 2.0 with JofraCal software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInsert dimensions\u003c\/th\u003e\n\u003ctd\u003e25.7 mm x 120 mm, brass\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\/temperature-calibrators\/ctc-series-compact-temperature-calibrator\" target=\"_blank\" rel=\"noopener\"\u003eAMETEK Calibration: CTC Series page\u003c\/a\u003e.\u003c\/p\u003e","brand":"Ametek Jofra","offers":[{"title":"Default Title","offer_id":67777126072507,"sku":"IMM_85648628","price":2684.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/ametek-jofra-ctc660-dry-block-calibrator-600x600-1.jpg?v=1792556841","url":"https:\/\/na.indomultimeter.net\/products\/ametek-jofra-ctc-660-dry-block-calibrator-28-to-660-c-compact-calibrator","provider":"Indo Multimeter","version":"1.0","type":"link"}
