The calibrator KAL 84 is used for calibrating pressure sensors. It represents a combination of a pressure generator (hand pump) and a pressure meter with digital display. The instrument provides a simple means for testing and calibrating both pressure sensors and complete pressure measuring equipment. High accuracy and excellent reproducibility, together with a specially rugged construction, provide the unit with all the properties required for laboratory applications.
After the unit has been switched on and connected to the pressure sensor to be calibrated (test object), the required pressure is set with the small hand-wheel. The built-in pressure meter measures the set pressure accurately and indicates it in digital form. Since the generated pressure is identical at the built-in pressure meter and at the test object, the pressure measured by the test object corresponds exactly to the pressure indicated by the KAL 84.
Models with different pressure ranges are available. Each model has an application-specific range (range 1) and can be switched to a corresponding SI range (range 2) in Pascal (Pa) or Kilopascal (kPA).
