Ametek APM CPF

Your Multi-Purpose   Signal Calibrator

Now Measure Pressure!
THE CRYSTAL APM CPF SERIES pressure module, with integrated CPF 
female connection, offers the functionality and flexibility to perform 
pressure calibrations with a multifunction signal calibrator. In addition, 
when connected to a hand-held pressure calibrator, the APM can 
expand its pressure range.
The APM is engineered to deliver the same high level of accuracy 
whether in the lab or in the field. Combined with calibrators and pump 
systems, the Crystal APM is a powerful calibration tool.

Key Features
?  Accuracies to 0.025% of Reading. 
Performance to meet almost any calibration and measurement task.
?  Seven Ranges Available. 
Full coverage from vacuum to 15 000 psi /1000 bar.
?  Rugged Construction. 
Machined aluminum housing. Engineered for rough field use–
almost unbreakable.
?  Self-Contained, Inligent Module. 
Calibration data is stored in the module, so any module can be combined with any compatible JOFRA indicator. No need to “calibrate” the 
module to an indicator.
Compatible with your existing JOFRA Calibrator
When combined with these JOFRA calibrators, the APM is a powerful calibration tool. 
ASC300/ASC301/ASC321/ASC-400/ASC-400

Lab Accuracy in the Field

Active Temperature Compensation
Count on the same accuracy at any temperature, between -20 and 50° C.

Calibrate with Confidence Anywhere
Take measurements with up to 0.025% of reading accuracy. 
Crystal Engineering calibration facilities are A2LA accredited, (# 2601.01) 
which is internationally recognized by ILAC

Pressure Calibration with a Signal Calibrator
The Crystal APM converts a JOFRA ASC400 multifunction signal calibrator 
to a full-featured pressure calibrator. Seamlessly integrated with AMETEK 
pump systems, an APM combined with an ASC- 400 provides the benefits 
of a host of features like leak-test, pressure-switch calibration, scaling, 
% error calculation, and more!
