Instrument description
2.1 Features
The KAL 84 is a portable device for calibrating pressure gauges. Typical applications
include calibrations of medical devices such as blood pressure meters, ventilators
and infusion pumps. The halstrup-walcher KAL 84 pressure calibration device is also
used in the manufacture of pressure sensors and pressure switches. Its sturdy
construction and rechargeable battery also make this instrument ideal for use in
assembling pressure transducers, as it allows the transducers to be calibrated on site.
Use of the KAL 84 for quality assurance purposes, e.g., as a transfer standard for test
equipment monitoring, is also becoming increasingly important.
The KAL 84 pressure calibrator consists of a pressure sensor, a liquid crystal display
and a transducer used to generate the desired pressure.
