The sample temperature is measured with a Pt100. For a measurement, the ball is lifted automatically to the tip of the syringe with a magnet and let loose so that the ball falls under the influence of gravity. The time of descent is measured with two optical transmitters. The wavelength of the emitter is in the near infrared at 950 nm to enable the viscosity determinations of darker and turbid samples. This ensures error-free operation even with samples that transmit only little radiation.
Optional accessories are computer and an external keyboard.
