MX7B
The MX7B is an active vacuum gauge (also called an analog vacuum gauge or a digital vacuum gauge) featuring the well-known Televac 7B cold cathode ionization gauge. This gauge provides robust, contamination-resistant measurement from 10-3 to 10-8 Torr. The Penning ionization gauge is easy to disassemble, making gauge replacement and cleaning stress-free while also saving you time and money.

Description
Our engineers designed this cold cathode ionization gauge with end users in mind, with a particular focus on heat treat and vacuum furnace end users who wanted full range vacuum measurement from a durable and cleanable digital vacuum gauge or analog vacuum gauge. The MX7B Penning ionization gauge is designed for use with our digital micron gauges, the MX4A convection active vacuum gauge or MX2A thermocouple active vacuum gauge, for a combined range of 10-8 Torr to 1000 Torr.
This system is also a drop-in replacement for the Televac® MP7ER cold cathode active vacuum gauge.
