JOFRA ETC Series dry-block calibrator
Easy Temperature Calibrator

This is probably the fastest dry-block calibrator in the world! Heats up by up to 100°C / 212°F per minute and completes a full dual-point calibration in less than 10 minutes, including stability time; timesavings at your fingertips! The ETC series is designed for field testing of temperature measurement devices. The small size and light weight make it a perfect instrument to verify sensors in difficult to reach places. All JOFRA ETC units have many of the same useful and timesaving features as the more advanced JOFRA dry-block series.

JOFRA ASC300 Multi-function calibrator
Advanced Signal Calibrator

The ASC300 is big enough to cover all your needs for a process signal calibrator with high accuracy and small enough to fit into your tool box and operate with one hand for easy field calibration. The ASC300 can change your entire calibration regimen for signal, pressure, and temperature. You can combine this versatile calibrator with the APM external pressure modules or a JOFRA dry-block calibrator to meet your calibration needs.
