Edwards APG200 High Performance Compact Pirani Gauge

Edwards APG200 series high performance compact Pirani Gauge is the perfect vacuum measurement solution across a spectrum of applications due to its compact size, LED light ring, integrated set points and flexibility of connections/outputs.

Edwards production facility in the UK has been making and designing vacuum gauging for decades. With this experience we have been able to develop a gauge that has a 25% reduced package size, with no loss in performance. And by owning not only the measuring technology, but also the electronic development and manufacture we have been able to maximize the features we can offer.

With a range of upgrades and feature enhancements, the Edwards APG200 is suitable for all vacuum markets, from analytical instruments who can take advantage of the reduced size and flexible outputs, to Semiconductor for whom the new interfaces and light rings enable better maintenance of systems, to Research and development for whom the local pressure indication helps to monitor experiments away from the main interfaces.

Measurement Range: ATM to 3.75×10-4 torr

Accuracy: Atmosphere to 100 +-50% | 100 to 1e-3 +-15% | 1e-3 to 5e-4 +-50%
