The Jofra ETC 400C is a dry-block calibrator that heats as quickly as 100°C per minute, stabilising in just 3 minutes, and can complete a 2-point test in less than 10 minutes. The calibrator operates in the 28-400°C range. Designed for field testing of temperature measuring devices the device is compact and lightweight making it suitable for verifying sensors in difficult-to-reach places.

All instrument controls are accessed directly from the front panel. The one-key-one-function logic means that there are no difficult multiple keystrokes to remember to access primary functions. The multifunction display shows actual and set temperatures, a stability indicator and a stability countdown timer.
The auto-stepping feature allows the operator to stay in the control room, or another remote location, monitoring the output from the sensor under test while the ETC-series calibrator is placed in the process and automatically changes the temperature using a programmed step value and rate. Up to nine different temperature steps and hold times may be programmed. This feature is also ideal for burning-in new sensors prior to installation. It is also useful for testing temperature dataloggers.
An RS232 communication interface is standard and the ETC 400 A is supplied with Jofracal calibration software, which allows the user to customise calibration routines.
The stainless steel and rubber side panels make the instrument suitable for operation in heavy-duty industrial environments.
