Ametek-Jofra Professional Temperature Calibrator PTC-155 (-25 to 155°C) or (-22 to 311°F)
The JOFRA® PTC-155 is a professional dry-block temperature calibrator makes it especially ideal for use in all industries temperature sensor calibration from (-25 to 155°C) or (-22 to 311°F). The PCT-155’s associate models provides precision Calibration temperatures from 33 to 350°C (PTC-350) and from 33 to 660°C or (91 to 1220°F) (PTC-660).
The JOFRA PTC-series features our well-known active dual zone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat dissipation throughout the entire calibration zone. The upper zone compensates for heat loss from the sensor-under-test and from the open top. This design also eliminates the need for extra insulation of sensors-under-test and makes it possible to calibrate any type of mechanical sensors.

Model Number Ordering System
The Ametek Jofra model number system consists of 1 choice of M0dels Numbers, 3 choices of Model Versions, 2 Choices of Main Power, 9 different available Power Cords, 8 types of Inserts, 1 DLC Sensor, 3 STS Reference Sensors, 7 calibration types and 3 Accessory choices. A representative P/N is PTC125B230ASMU1R16EATR which translates to JOFRA PTC-125 B with 230VAC, EU power cord, set of metric inserts, User Interface functionality, STS-150 reference sensor, full EA temp. calibration certificate, and carrying case with trolley & support rod.
The total number of available model numbers is then 1x3x2x9x8x1x3x7x3=27216 P/N’s. It borders on impractical to list all of the available models so please contact ATEquip for a price and delivery quotation. Refer to the part numbering system list on the datasheet to construct the exact PTC calibrator of your choice.
