Jofra is the inventor of the portable high-precision dry-block temperature calibrators. The range of Jofra calibration instruments covers precision thermometers, temperature baths, and high-accuracy temperature sensors. Our dry-block and liquid bath portable temperature calibrators include 6 series with more than 25 models spanning temperature ranges from -100 to 1205°C.
The RTC Series delivers the industry’s most advanced dry-block calibration performance. Built for professionals who require complete confidence, high stability, and a streamlined workflow from deep-cold to high-temperature operations.
The CTC Series covers an extensive temperature range across five different models. This broad range ensures the calibrator handles a variety of calibration tasks, from low-temperature food storage to high-heat industrial furnaces.
The PTC Series integrates a broad temperature range, high accuracy, stability, and speed within a robust, portable device. Perfect for critical calibration in pharmaceutical, oil and gas, and food processing plants.
Specifically designed for maritime applications including marine engine room equipment, ship HVAC systems, and offshore machinery. Provides stability of ±0.1°C for reliable onboard operation.
Heats up to 100°C per minute — Stabilizes in just 3 minutes!
The ETC Series is the ideal dry block temperature calibrator when time is the critical factor and rapid field checking is required. Small enough to fit in a tool bag, the ETC is the fastest field tester for verifying temperature switches, RTDs, thermocouples, and dial thermometers.
