The 7040 Digital Pressure/Current Calibrator is a portable device suitable for laboratory, workshop, and field operations. It has the capacity to calibrate process loop current and pressure. This device has a standard accuracy of 0.04% and displays pressure levels using nine engineering units. The units include PSI, bar, cmWg, KPa, inWg, mmHg, inHg, Atm, and Kg/cm2.
Its loop current can be presented in mA or as a percentage of coverage. The resented measurements can be accessed again by connecting the product to a PC or laptop using RS232 and other specific programs. The display is a 4.6 digit LCD which is powered by 9V PP3 batteries. Moreover, the unit comes with a pneumatic fitting, technical manual, RS232 lead, carry case and kits, and hose.
