CTC (Compact Temperature Calibrator)
The CTC Series is a compact, portable dry-block temperature calibrator designed for fast, on-site calibration of temperature sensors such as RTDs, thermocouples, and other probes. It replaces traditional liquid-bath calibrators, offering simpler handling, no need for hazardous fluids, and easier portability, making it well-suited for field use, maintenance workshops, and industrial environments.
Features
Wide temperature range across different models: from –25 °C to +1205 °C (–13 °F to 2201 °F), depending on model.
Reasonable accuracy (±0.2 °C) and good stability (±0.04 °C)
Fast heating/cooling and stabilization time
Compatible with a wide variety of probe diameters and sensor types
User-friendly interface and functions
Portable and lightweight make it suitable for industrial-site usage
