The ASM series (Advanced Signal Multi-scanner) offers a unique time-saving and automatic solution to calibrate multiple temperature sensors simultaneously. The ASM800 series is designed for use where ever temperature measurement is critical and/or there is a need for traceable calibration documentation.

The ASM series is a series of 8-channel scanners controlled by JOFRACAL  software through a PC. Up to 3 ASM units can be stacked to calibrate up to 24 sensors at the same time. It can handle signals from 2-, 3- and 4 wire RTD’s, TC’s, transmitters, thermistors, temperature switches and voltage. The solution includes the easy-to-use software JOFRACAL  to set up, exe-cute, print and save the valuable traceable calibration data - just connect the ASM to a PC through a RS232 cable.

JOFRACAL  controls all Ametek dry-block heating/cooling sources and includes the flexibility to use manual liquid baths, ice-points or dry-blocks. Connect the reference temperature sensor directly to the ASM800 or use your existing Ametek temperature reference device.
