This series of sensor can measure and transfer medium\'s pressure and
temperature at the same time. It can test the pressure and temperature of sealed space.
Its parameter can be calibrated by manual.
It can automaticallydetect the medium , in the meanwhile report the information
to the system.If the value is out of the standard，it will send alarm in time.
This series of sensor GPS, BD positioning function and report location informance in time.
It adopts precise pressure sensor and temperature sensor with high stability and reliability.
It combineds with high-performance transmitter special circuit，
and the overall performance is stable and reliable.
