The ETC series is designed for tests and verifications of temperature sensing devices in the field. This instrument is ideal when time is a critical factor and the highest accuracy is not a requirement. Reduced size and weight are important considerations as the unit may fit into a toolbox or instrument carrying case, and can be used for sensors that are difficult to access. The ETC calibrator 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.
One-key-one-function user interface provides immediate access to setting the temperature and the auto-step timesaving function. The stability indicator provides audible and visual prompts when the temperature is stable. This function also includes a 3-minute countdown before the stable condition. Stainless steel and rubber side panels make the instrument suitable for many years of faithful duty in an industrial environment.
One of the models – the ETC-400 R is designed for optimum speed in connection with calibration of infrared thermometers. The 36 mm (1.4 in) target provides the optimum size for reliable calibration of infrared thermometers in the process industry as it is designed for high accuracy and long-term stability while maintaining speed.
