TSI Multi Parameter Ventilation Meter in the United StatesInstrument Introduction:
The 9555 series is a portable and handheld multifunctional ventilation testing instrument. These instruments can be equipped with differential pressure sensors and multiple wide range, plug-in probes. Users can choose the most suitable probe from a variety of probes with different functions according to their actual testing needs. Simply plug in the probe to achieve multiple tests. These probes can measure wind speed, temperature, relative humidity, CO, and CO2. The parameters that can be calculated include air volume, heat flux, turbulence, wet bulb temperature, and dew point temperature.
