the 761 series portable automated pressure calibrators provide a turn-key solution for 

calibration of gauges, transmitters, and switches both in the field and in the laboratory. 

In a portable package, this calibrator can automatically generate pressures from 90% 

vacuum to 600 psi (40 bar) with 0.005% FS pressure control stability and 0.02% FS 

accuracy. To improve the calibrator accuracy, two pressure modules with differing 

ranges are built-in and integrated with the internal pump and controller.

The 761-LLP is specially designed for low pressure calibration, and pressures as low 

as 0.01 Pa (0.00004 inH2O) can be automatically generated and controlled.

The 761-BP is designed for barometric gauge calibration. With a quartz pressure 

sensor, the accuracy of 761-BP can achieve 0.01%FS accuracy.

With optional external pressure modules (160 series), the 761 can measure pressures 

up to 10,000 psi (700 bar) with 0.025%FS accuracy. In addition to the pressure 

generation, control, and measurement capabilities, the 761 also features HART 

communication capability, supplies 24V loop power, and reads the current or voltage 

produced by the pressure transducers. The 761 is a state of the art automated 

pressure calibrator which brings automated pressure calibration to the field.
