The Televac® MX4A Active Vacuum Gauge (also called a convection vacuum gauge, analog vacuum gauge, digital vacuum gauge, convection, or Pirani gauge) utilizes an easily replaceable Televac® 4A convection vacuum gauge. This digital vacuum gauge has a variety of features including a pressure measurement range from 1*10-4 Torr up to 1000 Torr, RS-485 communications, two programmable set points, and a selectable 0 to 10 V DC analog vacuum gauge output.
The bright OLED digital vacuum gauge display makes it easy to read from a distance. Options on this Pirani gauge can be set from four touch controls on the top of the unit or through RS-485 communications (or EthernetIP if you add in an EthernetIP gateway). This vacuum gauge offers an extensive selection of fittings, simple use, ease of sensor replacement, and low cost making it an excellent choice for a variety of vacuum applications.
