• Sourcing, simulating and measuring pressure, temperature and electrical signals
• Smartphone-like menu and interface make the operation simpler and easier
• The internal cold junction compensation sensor can be re-calibrated at ice point by users

The Additel 221A is very unique to the multifunction temperature calibrator market. Not only does it provide you with the ability to source, simulate and measure temperature and electrical functions but it also incorporates full documenting capability and many other solutions other products do not provide. As a standalone device, you can create tasks, run tests and store the results. With the use of Additel/Land Software or Additel/Cal software, all saved tasks and data can be downloaded and managed. With its unique internal could junction compensation sensor, cold junction compensation is very simple and easy.

A highly integrated Multifunction Temperature Calibrator featuring several patented technologies, the 221A is an ultra-compact, rugged, and easy to use the hand-held device for sourcing, simulating, and measuring temperature, and electrical signals. Its smartphone-like menu and interface make the operation simpler and easier. The 221A is ideal for calibrating, maintaining, and troubleshooting process instrumentations. Automation and documentation capabilities make the 221A a turnkey solution.

The ADT221A multifunction temperature calibrator is a process tool for measuring, sourcing, and simulating mA, mV, V, RTDs, thermocouples, ohms, frequency, and pulses, captures switch values, and provides 24 V loop power.
