Designed to provide a compact, lightweight, total pressure calibration solution for transmitters, gauges and switches, the 718 Pressure Calibrators feature a new design that protects the built-in pneumatic calibration pump from fluid contamination, allowing it to be serviced in the field for reduced service expense and overall cost of ownership. Measuring less than nine inches in length and weighing just over two pounds, the rugged unit is available in 1, 30, 100 and 300 psi models.
