PR280 electric ventilated wet-dry gauge uses the ventilated dry-wet bulb method to measure relative humidity, so as to avoid the effect of wind speed on the humidity. It can perform multi-point humidity calibration and further improve the measurement accuracy through modifying the wind speed and pressure values. It can also enter the dry-wet bulb sensor certificate value to achieve the sensor data correction. It uses 320×240 dot matrix large-screen LCD display, which can simultaneously display the relative humidity, dry bulb temperature, wet bulb temperature, pressure value, wind speed and other data so as to understand the data information at a glance.

  • Long term stability with wet and dry instrument
  • convenient to use with wet and dry instrument
  • wet and dry instrument of strong anti-interference capability
