The Martindale TEK300 is a loop calibrator that is ideal for use in process control and signal injection applications.

A single purpose calibrator, the TEK300 features the ability to source and measure modes from 0 to 20mA. It also includes a built-in sink function which also can go up to 20mA and uses a monitor mode to evaluate the current in a process loop.

The TEK300 is also extremely portable and ideal for field use in process control. It displays test values directly on the LCD screen built into the unit and also includes LED indicators in green and red colouring.
