Tai'an Nimeng Electronic Technology Co., Ltd.. welcomes you!
NM-TH300 Wall-mounted Intelligent Temperature and Humidity Recorder
The recorder is independently designed by our company based on the advantages of similar foreign products and the characteristics in our country. It can record the temperature and humidity parameters. The high-precision integrated temperature and humidity digital sensor imported from Switzerland is used to save the sampling data in the recorder memory. The collected and recorded data can be transmitted to the computer for processing, forming a computer temperature and humidity monitoring system. Power to the recorder is supplied by high-energy lithium battery. The power consumption of the whole machine is very small. External power supplies can be used. It is small and easy to carry.
NM-HUMI700 Standard ventilation psychrometer
Standard ventilation psychrometer is designed according to the principle of ventilation psychrometer. It is equipped with two temperature sensors, one for dry bulb temperature measurement and the other for wet bulb temperature measurement. The wet bulb temperature sensor is wrapped with gauze soaked in water. The evaporation amount of the wet bulb surface of the humidity temperature sensor depends on the relative humidity of the atmosphere, and the heat required for evaporation causes a decrease in the temperature of the wet bulb. The relative humidity is calculated by the humidity formula based on the factors, such as dry bulb temperature, wet bulb temperature and atmospheric pressure at that time. The motor drives the fan to ventilate the surface of the dry and wet bulb temperature sensor, so that the surface of the sensor can maintain a substantially constant wind speed. Thus, the humidity measurement will be more stable and accurate.
Michell Optidew Vision Precision Dew-point Hygrometer
The working principle of the precision dew-point hygrometer is based on the proven optical dew point measurement. It has unmatched long-term stability. When the ambient temperature is within -40℃ ~ + 90℃, it has a wide measuring range, equivalent to the relative humidity ＜0.5～100%. The optical dew-point hygrometer displays the measured humidity with high-definition digital display, provides dual current 4-20mA linear output. It is also equipped with serial communication interface, which can realize setting and monitoring from the appropriate computer and PLC, or through the specific data login software of the optical dew-point display hygrometer.
