• Temperature ranges: ATC-156 (-24 to 155°C); ATC-157 (-45 to 155°C)
  • High accuracy (4-wire True-Ohm-Measurement technology)
  • MVI Mains Variance Immunity
  • Universal inputs handle multiple type temperature sensors
  • Up- and download of work orders (calibrations)
  • RS232 and JOFRACAL calibration software
  • Marine approved temperature, pressure and signal calibrators


The dry block Ametek ATC-156/157 advanced temperature calibrators feature unique dual-zone heating blocks - designed for optimum performance and superior temperature homogeneity throughout the block. This new design has a performance equivalent to a liquid temperature bath. The Ametek ATC-157 advanced temperature calibrator features the widest temperature range for a cooling dry-block on the market today.

The four temperature ranges, which are the primary difference for the Ametek ATC advanced temperature calibrators, are:

  • ATC-156: -24 to 155°C (-11 to 311°F)
  • ATC-157: -45 to 155°C (-49 to 311°F)

Each dry block Ametek ATC advanced temperature calibrator may be used to perform fully automatic calibration routines without using an external computer. However, you can also use the computer for full upload and download capabilities. Units may also be supplied with inputs for external reference sensors and for sensors-under-test.
