The PCL1000 combines the functions of a high accuracy calibrator with the common multimeter; this single instrument will calibrate virtually any process device—read and source thermocouples, RTDs, resistance, voltage, current, frequency, pressure and test continuity as well. Optional PCL-PM external pressure modules (one PCL-PMA is required, sold separately) are available in ranges from 5 to 5000 psig, as well as vacuum, absolute compound and differential pressures.
