Ametek Jofra ETC-125A Temperature Calibrator
Overview
The Jofra ETC (Easy Temperature Calibrator) series is designed for field verification of temperature sensing devices where time matters and a heavy lab instrument is not practical. The ETC-125A covers -10 to 125 °C in a small, lightweight body that fits in a tool box, heating at up to 100 °C per minute and stabilizing about 3 minutes after reaching set point. A one-key-one-function interface with a backlit multi-information display keeps operation simple.
Pre-drilled holes accept an insertion tube, and auto-stepping programs up to 9 temperature steps with hold times for unattended runs. A stability indicator with a 3-minute countdown, a user-selectable maximum temperature limit, RS-232 interface and JOFRAcal calibration software come standard, and the ETC-125A runs on multi-voltage 115/230 VAC mains power.
Features
- Temperature range -10 to 125 °C (14 to 257 °F)
