Compact temperature and CO
2
concentracion transmitter
The transmitter measures the temperature and the
CO
2
concentration by a sensors located inside the
transmitter box, which is equipped with vents at the
top. The device is characterized by a simple
compact design, but a relatively longer response to
a step change of measured quantities than those
with an external probe. The instrument is placed
directly into the measured area. The transmitter is
equipped with an external power input and an slot
for 2nd battery,
allowing for extended battery
operation.
W8861
Transmitter with input for external probe
measuring
CO
2
concentration, with
internal temperature and atmospheric
pressure sensors
The transmitter measures temperature and
atmospheric pressure from built-in internal sensors
and CO
2
concentration from an external probe of
the CO2Rx/E series (not included). The transmitter
allows to measure higher CO
2
concentrations
(depending on the used probe) and with faster
response compared to devices with internal CO
2
sensor. Conversely, the response of the sensor to a
step change in temperature is relatively slow. The
CO2Rx/E probes provide calibrated readings and
are therefore interchangeable without interfering
with
instrument settings. The maximum
recommended probe length is 4 m. The transmitter
has increased protection against external influences
(dust, water, humidity) and is equipped with an slot
for 2nd battery,
allowing for extended battery
operation.
