Heart Rate/Exercise
The Exercise Heart Rate
sensor is ideal for determining the heart rate of active
people by measuring the heart rate before, during and
after exercise. The sensor is comprised of a wireless
transmitter belt and a Receiver module that plugs into
Fourier's EcoLog XL. Similarly to the
EKG, the Exercise Heart Rate sensor, specifically the
transmitter belt, senses the electrical signals generated
by the heart. Every heart beat sends an electrical signal
to the Receiver module, enabling the heart rate to be
determined.

Heart Rate/Pulse
The Heart Rate sensor monitors
the light level transmitted through the vascular tissue
of the fingertip and the corresponding variations in
light intensities that occur as the blood volume changes
in the tissue. It has two ranges: Waveform and Beats
per Minute.

Oxygen
The Oxygen sensor consists
of a galvanic oxygen sensitive electrode with a processing
unit (oxygen adaptor, equipped with a calibration knob).
The sensor can measure % O2 in air and is calibrated before every measurement.
The sensor is supplied
with a storage shorting cap. The probe is warranted for
12-months to be free from manufacturing defects and
to meet specifications. Improper storage without the
shorting cap voids the warranty. These probes have been
known to last for years with proper storage and use
of the shorting cap.

pH
The DT016 is a pH sensor
measuring the entire range of 0 to 14 pH. The DT016
consists of the Fourier Systems adaptor and
a pH electrode. The sensor is equipped with an automatic
temperature compensation system. In order to use temperature
compensation a temperature sensor can be connected to
the EcoLog XL along with the pH sensor.

Temperature
(-10 to 110°C)
The DT241 is a simple,
durable, temperature sensor. It connects directly to
the data logger using a standard mini-din cable. At
the end of the sensor cable there is a temperature probe,
covered with isolating material ensuring protection.
The DT241 measures temperature between -10 °C and
110 °C, and has an accuracy of ±1 °C. It
is mostly suitable for water and other chemical solution
temperature measurements.
