Overview
The CTC-652 covers 28 to 650°C (82 to 1202°F) and offers 190 mm immersion depth for long sensors. The JOFRA CTC Series is a compact dry-block calibrator for fast, accurate on-site work in oil and gas, pharmaceuticals, food processing, and HVAC. Across five models the series covers −25 to 1205°C (−13 to 2201°F), with accuracy up to ±0.2°C and stability of ±0.04°C. A large color display and one-key, one-function buttons provide automatic switch testing and auto-stepping. The CTC-652 offers 190 mm immersion depth for long sensors, and all C models include an input for an external reference sensor. MVI (Mains Voltage Immunity) circuitry maintains stability when supply voltage varies.
