Ametek Jofra PTC-660 A Temperature Calibrator
Overview
The A version has no reference or device-under-test inputs: the block is calibrated as a unit with a traceable certificate, and sensors under test are read with their own instrument. The color display, USB port and JofraCal software handle set points, auto stepping and documentation.
The PTC-660 uses active dual-zone temperature control for excellent well homogeneity, and a heat shield comes standard to protect the user at high temperatures. Intelligent STS reference sensors remain available as accessories if the workflow later moves to a B or C version.
Features
