2.3. FUNCTIONS OF THE INSTRUMENTS
The C.A 1821 and the C.A 1822 are thermocouple-based thermometers with one and two channels, respectively. They operate
with thermoelectric sensors of types K (Chromel/Alumel), J (iron/Constantan), T (copper/Constantan), E (Chromel/Constantan),
N (Nicrosil/Nisil), R (platinum-rhodium/platinum), and S (platinum-rhodium/platinum) and can measure temperatures from -250 to
+1767°C.
The C.A 1823 is a resistive-probe thermometer (PT100 or PT1000) having one channel and can measure temperatures from -100
to +400°C.
These instruments are easy to use. They have extensive stand-alone capabilities and can display:
temperature measurements in °C or in °F,
to record a minimum and a maximum in a specied period,
to record the measurements,
to communicate with a PC via a Bluetooth link or a USB cable.
The Data Logger Transfer software can be installed on a PC and is used to congure the instruments and to recover the recorded
measurements.
