The Ametek ATC-140 and ATC-250 advanced temperature calibrators feature designs that eliminate major uncertainties due to heat loss through the sensor-under-test and from the top of the block. The dry-block design combined with the external reference sensor input makes the Ametek ATC-140 and ATC-250 advanced temperature calibrators as accurate as a laboratory calibrator, but maintain the speed and portability of a dry-block.

The Ametek ATC-140 and ATC-250 advanced temperature calibrators measure the output from the sensor-under-test directly: thermocouples, RTD, mV, mA, and V and therefore doesn't require you to use multiple instruments. The Ametek ATC-140 and ATC-250 advanced temperature calibrators are fitted with a 160 mm deep well with a diameter of 63.5 mm (2.5 in) and can be used both as dry-block calibrators and as liquid calibration baths with a magnetic stirrer.

The temperature ranges for the Ametek ATC-140 and ATC-250 advanced temperature calibrators are -20 to 140°C (-4 to 284°F) and 28 to 250°C (82 to 482°F) respectively. Each ATC dry-block calibrator may be used to perform fully automatic calibration routines without using an external computer. You can also use the computer for full upload and download capabilities and further analysis of your data.
