Ametek Jofra PTC-660 B Temperature Calibrator
Overview
B models also provide switch test and auto stepping functions, with results shown on the color display and documented through JofraCal. Because the reference sensor carries its calibration data in an intelligent plug, swapping sensors does not disturb traceability.
The 660 model reaches 660°C in 20 minutes and cools below 100°C in 36 minutes, and a heat shield ships as standard for high-temperature work. The unit arrives with a multi-hole insert and the standard PTC delivery of cables, tools and software.
Features
- 33 to 660°C (91 to 1220°F) range
- ±0.15°C accuracy with external STS-150 reference sensor
- 4-wire true-ohm RTD reference input
- Device-under-test input for direct sensor reading
- ±0.04°C stability with active dual-zone control
- Switch test and auto stepping functions
- Plug-and-play intelligent reference sensors
- USB communication with JofraCal software
Applications
- Calibration of RTDs, thermocouples and transmitters
- Switch and thermostat verification with the switch test
- Documented plant temperature calibrations via JofraCal
