Direct, Absolute, Analog Pressure/Vacuum Measurement

photo - 690A Baratron Heated, High Accuracy Absolute Capacitance Manometer (0.1-1000 Torr), Temperature Controlled to 45 degrees C

The Baratron® 690A is designed for high accuracy pressure measurements with single-ended dual electrode/AC bridge instrumentation that is extremely stable and designed to minimize the effect of temperature changes. The 690A operates at an internal temperature of 45°C. By incorporating temperature control into the head, the accuracy is improved to as high as 0.05% of reading.

Features & Benefits:

  • Excellent thermal stability due to extremely low temperature coefficients
  • Highest accuracy pressure measurement instrument available
  • Six decades of measurement often eliminates several transducers with limited resolution

Applications:

The Baratron® 690A is designed for high accuracy pressure measurements in process or metrology environments.
