Ametek Easy Temperature Calibrator

Temperature ranges
ETC-125 A    -10 to 125°C / 14 to 257°F
ETC-400 A    28 to 400°C / 82 to 752°F
ETC-400 R    28 to 400°C / 82 to 752°F

Fast calibration saves money
Heats up as quickly as 100°C / 212°F per minute and stabilizes in just 3 minutes. Completes a 2-point test in less than 10 minutes

Extreme flexibility
The small size makes it perfect to store in a tool box and to check temperature sensors that are difficult to access

Fully-featured despite the small size
The multi-information display shows actual and set temperatures, a stability indicator, and a stability countdown timer

Timesaving features
Fast one-key-one-function access to set the temperature and the auto-stepping function

Heats up by up to 100°C / 212°F per minute and completes a full dual point test in less than 10 minutes, including stability time; time savings 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 time saving features offered in the more advanced JOFRA dry-block series.
