Introduction
DTBG Standard Electric Ventilation Psychrometer has high measurement accuracy and strong anti-interference ability, and can be used as a measurement standard; imported Pt100 platinum resistance is used as a temperature measurement sensor, and the temperature measurement is accurate and stable; the 5-inch color LCD touch screen can display Measurement data such as humidity, dry bulb temperature, wet bulb temperature, etc. Meet the new regulations "JJG993-2018 electric ventilation dry and wet meter verification regulations".
Function
☆ High measurement accuracy and strong anti-interference ability, can be used as a measurement standard.
☆ The relative humidity is measured by the ventilated dry and wet bulb method to avoid the influence of wind speed on the humidity measurement
☆ The imported Pt100 platinum resistance is used as the temperature measurement sensor, and the temperature measurement is accurate and stable.
☆ With multi-point humidity correction, dry and wet bulb temperature correction, wind speed, air pressure and other corrections, the humidity measurement range is wider and more accurate.
☆ The correction parameters of the dry ball and wet ball sensors are stored in the machine to eliminate the errors caused by the sensors deviating from the IEC index table.
☆ No warm-up is required when starting up, the system automatically starts up and self-calibrates, which is convenient to use and has good long-term stability
☆ With 5 inch LCD touch screen, full touch operation. It can display the measurement data of relative humidity, dry bulb temperature and wet bulb temperature at the same time.
