ASM Series Process Multi-Scanner
Brand: JOFRA CalibrationWe offer a signal multi-scanner which provides a time-saving, automatic solution to calibrate multiple temperature or pressure sensors simultaneously.
The scanner may be combined with our dry-block or liquid temperature calibrators, DTI temperature indicators, pressure calibrators, and ASC multifunction process calibrator.
Use any place where temperature and/or pressure measurement is critical and there is a need to create traceable documents for sensor calibration.
The Advanced Process Multi-Scanner offers unique time-saving and automation solutions to calibrate multiple pressure or temperature sensors simultaneously.
Each ASM contains an eight channel scanner controlled by Jofracal software on a PC. It can handle signals from 2-, 3-, and 4- wire RTDs, TCs, transmitters, thermistors, and temperature and voltage switches.
Up to 3 ASM units can be stacked to calibrate up to 24 sensors at the same time.
The ASM may be combined with any JofraCal compatible pressure calibrator, dry-block or liquid calibrators, DTI reference thermometers, and ASC multi-function process calibrators.
Use any place where temperature measurement is critical and there is a need to create traceable documents for sensor calibration.
Features- Automatic procedures reduce human error
- Dedicate one input channel to a reference sensor with accuracy to 0.026°C
- Uses True Ohm technology to eliminate EMF from cables, sockets, and sensors
- A models use a separate measuring unit as the standard, and B models have built-in measurement capabilities
- Combined with JofraCal or JofraLog you can:
- Set-up, execute, print, and save traceable calibration data
- Calibrate up to 24 sensors using a dry-block calibrator as the reference
- Calibrate using a high accuracy temperature reference probe directly with the ASM
- Data-log up to 24 sensors simultaneously
- Inputs for Thermocouple Calibration
