The Ametek Jofra PTC series Temperature calibrators provide precision temperature calibration of sensors, whatever the type or format. This is accomplished through an innovative active dual zone heating technology.
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 liquid-filled and other mechanical sensors.
The new USB connection provides fast and easy access to all laptops without the need of RS-232 to USB converters. Future-proof through e.g. a flash capability for easy firmware upgrades as well as already integrated LAN communication and USB host connectors for future use.
In order to comply with ISO, SOP's and FDA it is imperative that the calibration equipment never exceeds the expiry date of the calibration certificate. The PTC calibrators are constantly checking calibration dates on the calibrator as well as for the connected STS sensors. If the calibration period has expired, a warning will appear in the display. This feature prevents costly consequence evaluation.
The JOFRA STS-150 intelligent reference sensors contain individual calibration data regarding the sensor. This means that the time-consuming coefficient downloading sequence with risk of errors is no longer necessary and that the user can change the reference sensor and be up and running immediately. With the intelligent sensors, AMETEK has eliminated a source of error and the system is now giving a fail-safe plug'n'play calibration system.
