MX7M
The new Televac MX7M is an active vacuum gauge (also known as an analog vacuum gauge or a digital vacuum gauge) with the new Televac 7M cold cathode ionization gauge, which has a wide measuring range from 5*10-11 to 1*10-2 Torr (if you want to convert this value to another unit of measurement, check out our handy unit converter an). This is the only cleanable cold cathode on the market that measures in the range of 10-11 Torr. The new triple inverted magnetron design improves the overall accuracy of the vacuum gauge by improving linearity while significantly reducing the stray magnetic field.

Description
This vacuum gauge has all-metal seals, minimizing outgassing while maintaining a compact overall design. The MX7M cold cathode gauge also has a variety of features including a configurable 0 to 10 V DC analog output, RS-485 communications (EthernetIP optional), two programmable set points (relays and open collectors), and a bright OLED display with a 180° viewing angle.
All features of this cold cathode gauge are accessible through the display and touch controls or through the digital communications. Note that we also have an EthernetIP gateway for this active gauge which enables EthernetIP communication with a Rockwell Automation Allen-Bradley PLC. Combining this cold cathode gauge with a rough vacuum gauge such as the MX2A thermocouple active vacuum gauge or MX4A convection active vacuum gauge will provide full range measurement from 5*10 ®®-11 Torr to 1000 Torr (slightly above atmosphere).
