The Martindale TEK300 current calibrator is able to sink orsource a current up to 20mA. It is intended for process control instrumentation and general purpose signal injection applications.

A monitor mode facility is also incorporated into the design, whereby the current (0-20mA) in the process loop can be monitored and read directly from the digital display. The device is also fully protected against inadvertent misuse. This low cost unit offers an exceptional value for moneymeans of delivering and measuring 0 - 20mA currents. This makes it ideal for cost effective application in testing, calibrating and troubleshooting in a wide range of process control environments.
