Active Vacuum Gauge — Thermocouple / Pirani — 1×10⁻⁴ to 1000 Torr
The Televac MX2A Active Vacuum Gauge (also called a thermocouple vacuum gauge, analog or digital vacuum gauge, or Pirani gauge) utilizes an easily replaceable Televac 2A thermocouple vacuum gauge tube. This compact digital vacuum gauge features a bright, easy-to-read color OLED display, RS-485 communications, two programmable set points (open collector + relay), and a selectable analog output (7 ranges, 0–10 V DC). Its excellent resolution and repeatability, combined with ISO 17025 accredited and NIST traceable calibration options, make it ideal for general vacuum monitoring across a wide range of applications. Features and Benefits: • Low cost, very compact vacuum gauge • Easy-to-read color OLED digital display • Excellent resolution and repeatability (Pirani convection gauge) • Superior unit-to-unit performance • ISO 17025 accredited and NIST traceable calibrations optional • Pressure range: 1×10⁻⁴ Torr up to 1000 Torr • RS-485 communications with touch controls or software configuration • Two programmable set points (open collector + relay) • Seven selectable analog output curves (0–10 V DC) • Extensive fitting selection for easy integration
