Ametek Jofra CTC155A Temperature Calibrator, -25 to 155 °C Compact Dry-Block
Ametek Jofra CTC155A Temperature Calibrator, -25 to 155 °C Compact Dry-Block
Ametek Jofra CTC155A Temperature Calibrator
Overview
The CTC-155 A is the basic model, without external reference input, of Jofra's CTC series compact temperature calibrators. Designed for on-site and maintenance-shop calibration, it uses a dedicated temperature regulator for fast heating, cooling and stabilization, and its MVI (mains voltage immunity) circuitry keeps the block stable even when supply power fluctuates.
A large color display shows calibration status, and one-key functions cover Set, Preset, auto stepping and automatic switch testing. The 26 mm well with 120 mm immersion accepts a wide range of aluminum inserts, and the supplied JofraCal software documents RTD, thermocouple, transmitter and switch calibrations. It weighs only 5.5 kg.
