One transmitter, three
measurements
The Vaisala Combined Pressure,
Humidity and Temperature
Transmitter PTU300 measures
barometric pressure in two accuracy
classes, humidity, and temperature.
You can choose which probe
best suits your needs: PTU301 for
laboratories, PTU303 for outdoor
use, the warmed PTU307 probe for
demanding meteorology, and PTU30T
for pressure and temperature only.
Vaisala proven sensor
technology
The PTU300 transmitter uses sensors
known for their high accuracy
and excellent long-term stability:
the Vaisala BAROCAP® is used for
pressure measurement and the
Vaisala HUMICAP® for humidity
measurement. The temperature
sensor is a platinum RTD sensor.
