JOFRA ASC-400 is a portable process signal calibrator that provides the functionality and accuracy you expect from a laboratory calibration system, but compact enough to fit into the tool box and be operated with one hand for easy feld calibration.

JOFRA ASC-400 Multifunction Process Calibrator combines features such as %-error calculation, scaling, leak-testing, and switch calibrating into one multifunction process calibrator.

• Large full color display
• Advanced Simplicity user interface
• Simultaneous read-back and fast RTD simulation
• Connect an RTD to use as a high accuracy thermometer using “True Ohm” technology
• Full numerical keypad with cursor and function keys
• Recall saved tasks for both upper & lower windows
• Fuseless Protection
• Read and source RTD, Thermocouple, Current, Voltage, Frequency, and Resistance
• Calibrate gauge or absolute pressure when combined with an APM CPF pressure module
• Calibrate temperature when combined with a dry block calibrator
