Ametek Jofra ETC [ETC125AMULA01E] Dry Block Calibrator, -10 to 125°C,  Multi voltage 115 and 230 VAC EU w/Holes Metric Insert 1 x 12.5mm, 1 x 6mm, 1 x 4mm, 1 x 8mm and NPL & NIST Traceable Calibration Certificates. The Ametek ETC series portable temperature calibrators are specifically designed for tests and verifications of temperature sensing devices in the field. These instruments are ideal when time is a critical factor and the highest accuracy is not a requirement. Reduced size and weight are important considerations as the units may fit into a toolbox or instrument carrying case, and can be used for sensors that are difficult to access. The Ametek ETC series includes a One-key-one-function user interface which 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. The Ametek ETC series includes JOFRACAL calibration software which ensures easy calibration of RTDs, thermocouples, transmitters, thermo-swithes, pressure gauges and pressure switches. JOFRACAL software controls the complete calibration procedure, stores the results and provides a calibration audit trail through hard-copy certificates. All calibration data are stored for each sensor to monitor drift and optimize recalibration intervals. A scheduler feature allows planning of future calibrations. The ETC-125A is a dry block calibrator with a temperature range of -10 to 125°C. This model is a simple yet effective tool for verifying temperature instruments that also require references below ambient temperatures: e.g. air-conditioning and cold counters. The predrilled holes allow the use of an insertion tube in the largest bore. This increases the flexibility to match many sensor-under-test sizes.
