E27F Baratron® Capacitance Manometer with Etch Sensor
(0.1 - 100 Torr) Temperature Controlled to 45 Degrees C

photo - E27F Baratron Capacitance Manometer with Etch Sensor

The E27F is the solution for etch process-induced drift. Based on the industry-standard Baratron® capacitance manometer, MKS has developed structures in the sensor that nearly eliminate the deposition of process byproducts on the diaphragm, which minimizes drift. The E27F Baratron® manometer is temperature controlled to 45°C, accurate to 0.12% of Reading and includes updated temperature control electronics to provide superior long-term stability and repeatability. Optional heater and temperature status LED/switches indicate that the heater (which maintains the sensor temperature to 45°C) is in control. This capacitance manometer is available in Full Scale ranges down to 20 mTorr (0.03 mbar) to accommodate today's lower process pressures.

Based on established Baratron° capacitance manometer technology, the sensor's wetted surfaces are Inconel® for excellent resistance to corrosive gases. The contemporary stainless steel package provides a cleanroom-compatible product. The product is interchangeable with earlier 127, 627B, and E27B Baratron® capacitance manometers and can be used with MKS power supplies, display units and pressure controllers, or the user's compatible power supply/readout devices.

Features & Benefits:

  • Excellent long-term stability
  • Percent of Reading accuracy for more precise output signal in lower pressure ranges
  • Full Scale ranges low as 20 mTorr (0.03 mbar) for precise measurement of low pressure processes
