With accuracies down to ± 0.5°C and ranges from -10°C up to 400°C, 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 within 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.
