The dual-zone design pushes heating and cooling deep into the block, and Dynamic Load Compensation (DLC) offsets the energy drain of plugged-in sensors, so stability reaches ±0.005 °C.\u003c\/p\u003e\n\u003cp\u003eIntelligent reference sensors carry their calibration data on a plug and are recognized as soon as they are connected. Models B and C accept a reference sensor input and reach ±0.04 °C accuracy with the STS-200 sensor; the full-color VGA display, 0.001 °C resolution, USB communication and calibration-report function support accredited laboratory work.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRange -45 to 155 °C at 23 °C ambient\u003c\/li\u003e\n\u003cli\u003eAccuracy ±0.04 °C with STS-200 reference (model B\/C)\u003c\/li\u003e\n\u003cli\u003eStability ±0.005 °C\u003c\/li\u003e\n\u003cli\u003eDynamic dual-zone block with DLC\u003c\/li\u003e\n\u003cli\u003eIntelligent reference sensors with calibration data plugs\u003c\/li\u003e\n\u003cli\u003eFull-color VGA display, 0.001 °C resolution\u003c\/li\u003e\n\u003cli\u003eUSB communication and calibration reports\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCalibration of temperature probes and switches\u003c\/li\u003e\n\u003cli\u003eAccredited laboratory temperature calibration\u003c\/li\u003e\n\u003cli\u003eField verification of RTDs and thermocouples\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAmetek Jofra RTC157 Temperature Calibrator Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eRange (at 23 °C ambient)\u003c\/th\u003e\n\u003ctd\u003e-45 to 155 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy (ext.
