概要（Overview）

The Type 627D Baratron® is the RoHS-compliant version of the industry standard for stability and accuracy. The Type 627D Baratron is temperature controlled to 45°C, accurate to 0.12% of Reading and includes updated temperature control electronics to provide superior longterm 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.
