Features and Benefits
One push-button setting for the atmosphere
incredibly small, with a recessed electrical connector
Simple maintenance; replacement magnetron and Pirani elements separately
Available in low magnetic field version (SL) for extremely sensitive applications such as microscopy and mass spectrometry
extensive failure mode diagnostics infrastructure
Cable strain relief and improved ingress protection (IP44) are features of the D-type version that are compatible with Edwards TIC, TAG, and ADC controllers.
Magnetron employs a cutting-edge method for extremely dependable striking, even in situations with high vacuum or considerable contamination.
Automatic Pirani gauge element vacuum setting
Set point that is simple to program and covers the whole measuring range
Reduced HT voltage after ignition and low discharge current result in longer service intervals and gauge lifetime.
Microprocessor signal processing provides linear output in addition to a smooth transition between magnetron and Pirani outputs.
