ETC Easy Temperature Calibrator

Brand: JOFRA Calibration

The ETC Series is the ideal dry block temperature calibrator when time is the critical factor and the highest accuracy is not a requirement.

The block heats up to 100°C per minute and stabilizes in just 3 minutes! The small size and light weight, fit perfectly in a tool box, making it the perfect field calibrator to verify sensors in difficult to reach places.

Rugged construction, featuring stainless steel and rubber side panels, make the instrument suitable for many years of service in an industrial environment.
