The Extech 412355A is two calibrators in one: this product is both a current and voltage calibrator, capable of providing being a 0 to 24mA current and 0 to 20V voltage calibration source.
Ideal for a wide variety of tasks including setup and calibration of process devides such as transducers, indicators, recorders and controllers, the Extech 412355A is easy to setup, easy to control and has five stored calibration values to speed up calibrations.
The 412355A is part of the Extech Oyster series. These are named for their clamshell-like shape; the calibrator's lid can be flipped shut when not in use, making it pocket-sized and extremely portable.
Extech's Oyster calibrators also include a large-size LCD display which can show readings in mA or as a percentage of the 0 to 24mA range, or as mV for voltage. A built-in touchpad system also makes it easy to adjust the calibrator as needed to cater for different applications.
