Jofra ASC-400

The ASC-400 is a portable process signal calibrator that provides the functionality and accuracy you expect from a laboratory calibration
system but still compact enough to fit into a toolbox and operate with one hand for easy field calibration. The ASC-400 is more than just a
signal calibrator. Combined with our APM external pressure modules or our dry-block calibrator, it will calibrate pressure and temperature.
With its function and cursor keys, the full numerical keypad provides a simple and quick user interface; and the full-color display offers superior
visibility and overview. Sturdy construction, state-of-the-art circuitry, and fuseless protection ensure the ASC-400 will deliver consistent high
