Ashcroft ATE Handheld LCD Digital Calibrator

Handheld LCD Digital Calibrator

The Ashcroft® ATE-100 is a calibration system with a vast array of capabilities. These capabilities extend far beyond those of precision pressure measurement. The base unit contains a wide variety of application-specific firmware as well as the ability to measure both current and voltage inputs. In addition, this unit has the ability to interface the system with a computer, data acquisition system or dumb terminal via the standard.
