Interchangeable CASSY sensors make it possible to measure many different biological quantities including the following:
  • Pulse
  • Skin resistance
  • Blood pressure
  • Reaction time
  • Hearing threshold
  • pH value
  • Temperature
  • climate-related parameters (relative humidity, illuminance, atmospheric pressure, height)
  • O2 and CO2 concentration
  • Voltage
  • Current

The sensors are detected automatically and the corresponding measuring range is displayed automatically in the large digital display. With integrated loudspeaker, e.g. for measurement of the auditory threshold or to give an audible sound while pulse or blood pressure measurements.
The calibration of pH, O2 and CO2 concentration is internally saved and only needs to be checked from time to time. Additionally it is possible to connect the measuring instrument via the USB port to a computer. Including software for recording and evaluation of measurements.

Technical data

  • Measuring ranges: dependent on sensor

  • Height of digits: 25 mm
  • USB-port: compatible to USB 1.1 and 2.0, full speed, electrically isolated (USB cable included)
  • Supply: 230 V, 50/60 Hz
  • Dimensions: 20 cm x 21 cm x 23 cm
  • Updates: available free in internet
