Ashcroft ATE Handheld LCD Digital Calibrator

Handheld LCD Digital Calibrator
ATE

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.

• Interchangeable pressure and temperature modules
• Pressure measurement accuracies of ±0.025,0.05 and 0.10%, or .06/.07%
• Pressure ranges from 0.25"H2O to 10000 psi
• Supports most standard RTD probes and thermocouples
• Min/max, tare, flow, leak, programmable damping, percent function, trip detect, all standard
• High static DP measurement capability
• Optional: FM Approval for Class I, Div. 1, Groups A, B, C & D hazardous areas Data logging, Hi/low alarm relays
