The Omega® CA450 Process Multimeter is a portable test instrument to combine a digital RMS multimeter and a loop calibrator to give process technicians the same functionality in one tool. The model CA450 provides 24V loop power, reducing the need for carrying a separate power supply when performing transmitter testing. And with its built-in, selectable 250? Hart resistor, it also eliminates the need for a separate resistor. Process technicians can now do the same job while carrying less equipment. * For details visit omega.com\/ir-usb.
