Ventilation dry wet bulb thermometer for measuring air humidity, temperature and humidity sensor

Description :

　　1、 Introduction to DHM2 Ventilation Dry Wet Ball Temperature Gauge Instrument:

　　The DHM2 mechanical ventilation psychrometer is suitable for measuring the temperature and humidity of the air at meteorological stations and relevant departments; Suitable for meteorological and environmental protection, agriculture, laboratories, scientific research and other units. And installed in the calibration box as a humidity standard

　　2、 The main features of DHM2 ventilated dry wet bulb thermometer are:

　　The DHM2 mechanical ventilation dry wet meter adopts the principle of mechanical ventilation in its structural design, which stabilizes the velocity of air flow around the instrument ball within a certain range, thereby improving the accuracy of humidity measurement. It is currently a good instrument for measuring air humidity. Due to its ease of carrying and use, it is widely used by meteorological, environmental protection, health and epidemic prevention, coal mining and other departments for measuring air humidity.

　　3、 Technical parameters of DHM2 ventilation dry wet bulb thermometer:

　　1. Environmental temperature: When measuring air humidity, it can work normally in an environment of -10 ℃ to+45 ℃;

　　2. Humidity measurement range: 10% to 100% RH;

　　3. Scale and measurement range of thermometer: -36 ℃ to+46 ℃ and -26 ℃ to+51 ℃;

　　4. Working hours: The total operating time of the ventilator shall not be less than 9 minutes;

　　5. Net weight of the instrument: 1kg;

　　6. Ventilation speed: After the ventilator is turned on, the ventilation speed around the temperature gauge ball should not be less than 2.5m/s at the end of the fourth minute; At the end of the sixth minute, the speed should not be less than 2.2m/s; At the end of the sixth minute, the change in ventilation speed per minute should not exceed 0.2m/s;

　　7. Dimensions: 90.5mm x 415mm.
