High Accuracy Pressure Standard

Advance Pressure Calibrator

( Dwyer )

General

The JOFRA APC calibrators are the latest in the new generation of AMETEK handheld pressure calibrators. This series was designed to meet high accuracy pressure calibration applications and to make your tasks easier. The APC offers features such as dual information display, 17 different pressure units, transmitter supply, scalable mA input for % error calculation, serial communications, and external pressure module capability. The accuracy of the APC calibrators is deadweight caliber throughout the range and is temperature compensated for operation in controlled or in process applications. This is a truly superior pressure calibrator. The JOFRA APM series of pressure modules extends the application base for the APC calibrators by allowing for calibrations in ranges other than those of the indicator; and at a lower cost than purchasing another APC. The APM modules are also compatible with several other JOFRA calibrators. You can perform a calibration locally without returning the APC unit to the manufacturer. All you need is an accurate pressure reference. If you do require factory calibration, the pump and indicator are independent and only

the indicator needs to be returned.
