AMETEK PTC155A Temperature Calibrator

The Ametek 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.
