The Baratron® Etch Sensor Manometer is the solution for etch process-induced drift. The RoHS-compliant E29F helps eliminate process byproduct deposits on the surface of the diaphragm, minimizing drift. The E29F Etch Manometer is temperature controlled to either 45°C or 100°C, and includes efficient temperature control electronics to provide superior long-term stability and repeatability. It has an optional external zero input, which accepts a voltage equal to and opposite to the zero offset, to provide a zero output at zero pressure. The optional "At Temperature" LED/switch indicates that the sensor is at the controlled temperature.

Features & Benefits:

  • Percent of Reading accuracy for precise output in low pressure ranges
  • Full Scale ranges low as 20 mTorr for precise measurement of low pressure processes
  • Measures total pressure directly, independent of gas composition
  • Inconel® wetted surfaces are corrosion-resistant
  • Integrated sump for particle protection
  • Fast warm-up time
  • High overpressure rating for improved reliability


The Baratron® E29F is specifically designed for difficult etch and chemical vapor deposition (CVD) processes that can cause sensor contamination.
