Ametek Jofra PTC660A Temperature Calibrator
Overview
The PTC-660 A is the entry model of JOFRA's PTC professional dry-block calibrator series. It heats from 33 to 660 °C, and its patented active dual-zone block keeps temperature homogenous across the calibration zone, so sensors down the length of the well see closely matched conditions.
A large 5.7-inch colour VGA display keeps SET, READ, TRUE and sensor-under-test values visible during calibration, and MVI (Mains Power Variance Immunity) holds temperature stable even on fluctuating supplies. USB 2.0 communication, bundled JofraCal software, IRI recalibration reminders and multi-hole insert kits make field calibration efficient; this unit is the 115 V version.
