APG100 series Active Pirani Vacuum Gauges are available in 2 models. The APG100-XM is the standard model and measures to 10-3 mbar, the APG100-XLC is a corrosion resistant version with measurement to 10-4 mbar. Both gauges feature compact size for easy installation, a linear output and a replaceable sensor tube. These gauges are compatible with all Edwards TIC instrument controllers and other Active gauge controllers and displays.


• Cable connections and gauge adjustment conveniently located, thereby minimising the space envelope required for access
• Sensor tube can be baked to 150 °C
• Adjustable set-point for simple process control and interlocking
• CSA, C/US Approved
ശ Meets safety requirements for electrical equipment for measurement
• Linear output – 1 Volt per decade for easy interface with vacuum control systems
• NW16, NW25 and DN16CF flange options for easy connection to vacuum systems
• LED status indicator shows normal and fault conditions
• Remote calibration possible
• Replaceable sensor tube/electronics lead to a low cost of ownership
• Tool-less replacement of spare parts
